This is an interesting hypothesis that I came across recently. A theory that Moses (of Old Testament fame)and the Egyptian Pharaoh Akhenaten were the same person. It implies that Moses/Akhenaten was brought up by Israelite relatives, that his mother was the daughter of the OT prophet Joseph, that he ruled Egypt for seventeen years, enraged the Egyptian people by replacing Egyptian deities with one god(monotheism), and was forced to give up his throne. He moved to Sinai with his Israelite and Egyptian followers and came back years later to try(unsuccessfully) to regain the throne of Egypt.One intersting point was the last mention of Moses in the OT. In II Kings, 18:3-4 it states, "And he did that which was right in the sight of the Lord,according to all that David his father did. He removed the high places and brake the images, and cut down the groves, AND BRAKE IN PIECES THE BRAZEN SERPENT THAT MOSES HAD MADE; for unto these days the children of Israel did burn incense to it". This reference is eye catching(which is why I used upper case letters to emphasize it) because a staff topped by a bronze serpent was the symbol of Pharaoh's authority. Another interesting point was his name. Moses' name in Hebrew is written "Moshe". The Hebrew word m sh a does not mean what the biblical editor said that it did. In order for the name to mean,"one who is drawn out of the water",his name should have been "Moshui". A final point is the letter S at the end of the name Moses is drawn from the Greek translation. After Akhenaten fell from power, his name was forbidden to be spoken. It is supposed that the Israelite/Egyptian followers called him "Mos", meaning "the son", to indicate that he was the legitimate son of Amenhotep III(not his coregent Semenkhkare,who BTW was also murdered), and the rightful heir to his fathers throne. Akhenaten adapted the Heliopolitan solar form of the Egyptian temple- the same form used by Moses in the desert- to be used as the place of worship. Akhenaten also established animal sacrifice to his new God, just like Moses did. Moses introduced the ark to hold the Pentateuch scrolls in Exodus 25:10. This again was an Egyptian practice. Instead of cherubs at the top, it was usually a statue of the Egyptian god Anubis instead. Another curious topic was when the ten commandments came up. They are eerily similar to text in the Egyptian Book of the dead. The commandments are said to be a positive form of the Egyptian Negative Confession. It appears as though Akhenaten turned the moral code according to which the Egyptians believed their dead would be judged into a code of behavior for his followers in everyday life. Unlike other Egyptian deities, Moses/Akhenaten preached about a god who had no visible image. At any rate, true or not, it definitely got my gears turning and was a great read. I recommend reading the book to further your own investigation. It makes you wonder though.........
