|Children are typically told that a man named Moses wrote the Pentateuch, i.e. Genesis, Exodus, Leviticus, Numbers, and Deuteronomy; the last of these, i.e. Deuteronomy 34:5-6, however speaks of the burial of Moses and that no one knows where his grave is? This indicates that the Pentateuch was NOT written by a person named Moses.|
In 1582, Noel Journet asked the obvious question of how the Pentateuch, aka the Five Books of Moses (Genesis, Exodus, Leviticus, Numbers, Deuteronomy), could have been written by Moses, as we are told they were, if the fifth book, of the series, specifically Deuteronomy 34 (Ѻ), describes Moses' own death?
In c.1650, Samuel Bochart, while working on the Bacchus-Moses connection (see: Osiris, Dionysus-Bacchus, and Moses), noted that they both were buried in unknown tombs.  The 300AD Biblical story of Moses describing his own death and burial in an unknown tomb, in short, is an Osiris, Dionysus-Bacchus rescript.
In 1784, Ethan Allen, in his Reason: the Only Oracle of Man, gave his humorous take on the Moses pens his own death problem as follows: 
“This [Moses] is the only historian in the circle of my reading, who has ever given [Deuteronomy 34:5-8] the public a peculiar account of his own death, and how old he was at the decisive period, where he died, who buried him, and where he was buried, and withal of the number of days his friends and acquaintances mourned and wept for him. I must confess I do not expect to be able to advise the public of the term of my life, nor the circumstances of my death and burial, nor the days of the weeping or laughing of my survivors.”
In 1794, Thomas Paine, in his The Age of Reason, stated the following: 
“These books are spurious and Moses is not the author of them. They were not written in the time of Moses, nor till several hundred years afterwards; they are an attempted history of the life of Moses.”
In 1829, Thomas Cooper, in his Fabrication of the Pentateuch: Proved by Anachronism Contained in Those Books, citing Benedict Spinoza (Tractatus Theologico Politucs), Spanheim (Dubia Evangelica), Pere Simon (Historie Critique dis Vieux Testament), and Constantin Volney (Recerches Nouvelles sur l’History Ancienne, Volume One), summarized the Moses authorism issue as follows: 
“I. In the 34th chapter of Deuteronomy, ver. 5, 6, it is said, " Moses the servant of the Lord died there in the land of Moab, according to the word of the Lord. And he buried him in a valley in the land of Moab, over against Beth-peor; but no man knoweth of his sepulchre unto this day." It is manifest Moses could not have written this account of his own death and burial; but there is no hint or suggestion that it has been subsequently added to the main narration. The phrase, "unto this day," implies a considerable time past between the event narrated, and this narration of it. This is not a solitary passage that might have been interpolated at the end of the book; for it is so often repented that it is interwoven with the book itself. Thus, Deut. iii. 14, "unto this day." Gen. xxii. 14, "to this day."”
In 1996, Gary Greenberg, in his 101 Myths of the Bible, touches on the "odd" claim that the location of the grave of Moses (the PURPORTED author of Deuteronomy) is unknown "unto this day", which indicates that that this passage, Deuteronomy, and or the entire Pentateuch were NOT by Moses. 
In 2007, Christopher Hitchens, in his God is Not Great, citing Paine (1794), digress on the Moses problem as follows: 
“No one knows, says the author, "unto this day," where the sepulcher of Moses lies. It is added that there has since been no comparable prophet in Israel. These two expressions have no effect if they do not denote the pas-sage of a considerable time. We are then expected to believe that an unspecified "he" buried Moses: if this was Moses himself in the third person again it seems distinctly implausible, and if it was god him-self who performed the obsequy then there is no way for the writer of Deuteronomy to have known it.”
The solution to the so-called “unto this day” problem is resolved in the fact that Moses never existed, per reason that he is an Osiris rescript, as evidenced by the fact that Osiris, Dionysus-Bacchus, and Moses all have the same characteristics, attributes, and story-lines.
