|Through comparative mythology it can be shown that the Egyptian myth of the birth of the sun (Ra) out of the land mound (Nun) following a great flood (annual 150-day Nile River), a model that came to be known as Anunian theology (Ra theology), forms the backbone to 73 percent of modern religions (Ab-ra-ham-ic / B-ra-hma-ic faiths), and hence the historical origins to modern man's ideas about God, soul (negative confession), spirit, the creation of humans (creationism) (creation from clay), and most importantly belief in the theory of "life" and "death", concepts that do not exist in the framework of modern physics and chemistry.|
“The theological dependency of Christendom on ancient Egypt is much stronger than its theological link with the Hebrew tradition.”— Karl Luckert (1991), Egyptian Light and Hebrew Fire 
“The prominence in the texts of Asclepius, a thinly-disguised Imhotep, suggest an association with Heliopolis ... Although even the Pyramid Texts fail to set out the beliefs of Heliopolis systematically, why should we expect them to? After all, the people who mattered—the priests and worshipers—were already familiar with their own religion. The Texts do, however, allow the core theology and cosmology behind them to be reconstructed. The most successful attempt is found in Karl Luckert’s Egyptian Light and Hebrew Fire (1991), which isolates two related aspects: the overall understanding in the origins and nature of the cosmos, and its relationship to human beings.”— Lynn Picknett and Clive Prince (2013), The Forbidden Universe: the Occult Origins of Science 
The parent religion to 72 percent of the worlds religions, according to comparative mythology studies (as depicted adjacent), is the Egyptian religion sun god (Ra) worship religion Anunian theology (Ra theology), which originated primarily in the ancient Egyptian city of Heliopolis, the "city of the sun", in circa 3100BC, during which year the 20 nomes (cities) of lower Egypt united with the 22 nomes of upper Egypt to form the Egyptian first dynasty, an empire that would go on to dominate the world, both militarily and religiously, for nearly 3000-years. 
One of the reasons for necessity of the study comparative religion and mythology, in the context of the hmolsciences, is that the subjects of human thermodynamics, human chemistry, and human physics, and the principles derived therefrom, are the replacements for the older mythology-based modern religions, and thus when addressing questions about purpose, existence, meaning, and morality, etc., it becomes requisite to have some semblance of historical basis.
In plain speak, a typical layperson (atheist, agnostic, secularist, or religious) will ask queries such as what do modern thermodynamics, chemistry, and physics have to say about terms such as soul, spirit, life, death, purpose, existence of god, etc., whereby it becomes imperative if one is to give cogent answers to such questions to have an semblance of an of historical framework to the etymologies of these various terms and older proto-scientific theories. Without such pause for historical digression, many modern hardened scientists will waste decades searching for baseless ideas, such as the origin of life, whereas in fact "life" is a religious-mythological theory and not one that holds in modern hard science (where things are viewed as atoms and molecules, which are not, by definition, considered to be alive).

It is difficult to say exactly when the field of comparative mythology, in regards to the de-riddling of modern religion, arose as a distinct subject.
In circa 230, Alexandrian scholar Origen (185-254) penned the following: (Ѻ)
“To what person of intelligence, I ask, will the account seem logically consistent that says there was a “first day” and a “second” and “third,” in which also “evening” and “morning” are named, without a sun, without a moon, and without stars, and even in the case of the first day without a heaven (Gen. 1:5-13)? …. Surely, I think no one doubts that these statements are made by Scripture in the form of a type by which they point toward certain mysteries.”
The first two thinkers to have completed massive studies on comparative mythology and modern religion were Dutch theologian Gerardus Vossius, whose works as of 2008 have never been translated from the Latin, and French bishop Pierre Huet (1630-1721). 
French genius Voltaire (1694-1778), cites both Vossius and Huet, and concluded, among other things, that Moses is a re-write of the Roman god Bacchus (400BC-400AD). 
In 1770, German polymath Johann Goethe completing a dissertation (rejected on the grounds that it was unorthodox) on “The Legislature, On the Power of the Magistrate to Determine Religion and Culture” at the University of Strasbourg, in which he contended, among other things, that “Jesus Christ is not the author of Christianity, but rather a subject composed by a number of wise men and that Christian religion is merely a rational, political institution.” 
In 1803, French writer Charles Lebrun, in his Doubts of Infidels, as cited by Dorothy Murdock (2009), stated: 
“The history of Moses is copied from the history of Bacchus, who was called Mises by the Egyptians, instead of Moses. Bacchus was born in Egypt; so was Moses... Bacchus passed through the Red Sea on dry ground; so did Moses. Bacchus was a lawgiver; so was Moses. Bacchus was picked up in a box that floated on the water; so was Moses.... Bacchus by striking a rock made wine gush forth... Bacchus was worshipped...in Egypt, Phenicia, Syria, Arabia, Asia and Greece, before Abraham‘s day.”

See main: Rosetta stoneIn 1799, during a French expedition to Egypt, the famous tri-lingual inscribed Rosetta stone was discovered which aroused widespread public interest with its potential to decipher the hitherto untranslated Ancient Egyptian hieroglyphic language.
In 1820s, English physicist Thomas Young and French scholar Jean Champollion, translated the stone, after which modern comparative mythology and religion scholars began to emerge.
Soon thereafter, people began to see clearly that the main tenets of the major modern day religions (Christianity, Islam, Hinduism, etc.) originated from the core tenets of Egyptian mythology, those upon which the pyramids were built, particularly the story of the birth of the sun (sun disc) (later sun god Ra) out of the water or chaos / primordial mound of of beginning (later god Nun).
In 1883, English Egyptologist Gerald Massey published his The Natural Genesis (among other works), wherein he began to debunk a number of Bible mythologies, focusing on the overlaps of Horus and Jesus; a noted opening quote is: 
“It takes the latter half of all of one’s lifetime to unlearn the falsehood that was instilled into us during the earlier half. Generation after generation we learn, unlearn, and re-learn the same lying legendary lore. Henceforth, our studies must begin from the evolutionist standpoint in order that they mat not have to be gone over again.”
This issue of religious syncretism became definitively clear to the inquisitive thinker when in 1895 Egyptologist Wallis Budge published The Egyptian Book of the Dead (Papyrus of Ani), wherein after “untold numbers of people began to write books, papers, and dissertations on the parallels between Jesus and Osiris (Ra’s great grandson). 
|A depiction of the transformation of the Egyptian sun birth theory into the story of Noah and the ark.|
Nun | Nu = Noah
The Christian story of man named Noah landing on an mountain, following a flood, following the release of three doves, after which the sun shines, is a monotheistic rewrite of the Egyptian theory of the birth of the sun (Ra) following the primordial flood (150-day Nile River flood), out of a land mound (pyramid) Nu, that rises out of the flood, the sun being carried through the sky by a heron or "phoenix" as Herodotus described things.
In Hinduism, this was described as the story of Ma-Nu.
Abraham | Brahma = Ra
See main: Abraham and BrahmaIn 2004, American electrochemical engineer Libb Thims, after reading through the work of Gary Greenberg (among other works), independently arrived at the conclusion that the Abraham/Brahma theologies (Ab-ra-ham-ic faiths / B-ra-hma-ic faiths) are re-writes of the older Egyptian "Ra born of Nun" origin of the universe model/theologies, as hidden in their respective stories and name etymologies. 
One of the more significant unifying decipherments is the connection between the similarities of Jewish-Christian-Islam patriarch Abraham and the Hindu creator god Brahma, which overlap in at least six ways:
(a) Both Abraham and Brahma are the said-to-be creators all humans (Ra is the main creator god of the Egyptian pantheon).
(b) Both Abraham and Brahma have the same etymology: “Father Ra son of Nun” (water-fire-earth theory).
(c) Both Abraham and Brahma derived from the Nun (Noah and Ma-Nu, respectively).
(d) Both Abraham and Brahma have the same sister-wife, in namesake, Sarai and Saraswati, respectively.
(e) Both Abraham and Brahma have the same thrice sister-wife parable (creation by incest rewrite).
(f) The slaying of son reoccurs in both cases (release of the soul rewrite / Osiris-Horus splitting rewrite).
In 1975, American mythologist Lloyd Graham, in his Deceptions and Myths of the Bible, stated: 
“Abram is but the Hindu Brama, with a as prefix instead of suffix; and Brama was the original name of the Hindu creator. Later the letter h was added, thus making it Brahma. The letter h signifies life, and thus did Brama, Abram, and Sarai in due time receive life, or being, which implies that in the beginning they did not have it.”
All of this "letter change signifying life", to summarize, was re-written in the Bible as stories of god changing each person’s respective name, for some unspecified reason, whereas the original etymology is one of the Egyptian origin of life theories.
The 1996-2000 work of American religious scholar and Egyptologist Gary Greenberg seems to have been the first to explain points (e) and (f), such as in his chapter sections "Abraham pretended that Sarah was his Sister" (2000) and "The Osirian Iconography in Isaac's Sacrifice" (1996). 
In 2009, religio-mythology scholar Dorothy Murdock, in her book The Gospel According to Acharya S., penned a section entitled “Abraham is Brahma? Moses is Dionysus?”. 
Jesus = Osiris/Horus
The story of the the death and resurrection of a person named "Jesus Christ" said to have conceived of virgin birth, from a virgin women named Mary, via impregnation with the "holly spirit", is a monotheism rewrite of the polytheistic story of the death and resurrection of Osiris by the help of his god-wife sister Isis or Stella Maris (aka "star of the sea") and their sun Horus. Some of this is outlined adjacent.
|A snapshot of the how the Egyptian model of the resurrection of Osiris was re-written, in Christianity, into the resurrection of Jesus, and, in Hinduism, in to the reincarnation of Buddha. |
Sarai (Sarah) | Saraswati = Sirius (star)
The subject of the etymological origin of the character Sarai (Sarah), Abrahamic-version, or Saraswati , Brahmaic version, is generally traced to the Sirius, the brightest star in the sky, whose helical rising (following a 70-day absence from the sky), marks the start of the annual flooding of the Nile River.  All of this data of measured and observed natural phenomena formed the basis for Egyptian theology.
In 1830-33, reverend Robert Taylor discussed the connections between Sarah, Sirius (Dog Star), and the start of the annual flooding of the Nile.  Similar summaries were given by Logan Mitchell (The Christian Mythology, 1842) and Herbert Hardwicke (The Popular Faith Unveiled, 1881).
American religious scholar and Egyptologist Gary Greenberg gives the best account as to why the wife-sister parable is repeated three times, which is to cover-up the three unsavory points of creation by incest in the Heliopolis Ennead creation myth. 
American religious scholar and Egyptologist Gary Greenberg’s well-researched 2000 book 101 Myths of the Bible, wherein he steps through the nearly ever story in the Bible and shows the original Egyptian version (Pyramid texts + Coffin texts), from which these stories (Bible, Koran, Rig Vida, etc.) originated, is one of the best modern comparative mythology books. 
In 2009, Canadian lay Egyptologist John Pippy, in his Egyptian Origin of the Book of Revelation, attempts to argue that entire structure of the Book of Revelation, one of the final books of the New Testament, can be accounted for in the organization of text and paintings on the walls and ceilings of the tomb of Ramesses VI in Egypt's Valley of the Kings.

One of the easiest ways to explain "comparative mythology and modern religion" is visually. The best example is the 5,000-year artistic and conceptual evolution of the "halo" which originated from the myth of the sun or rather "sun disc" being carried through the sky by a bird (called the benu bird or phoenix) who balanced the sun on its head, and how this evolved over time into the halo, and then eventually the "thorns" depicted on the head of Jesus during the crucifixion.
