Egyptian Famine Lasted Seven Years is a Myth because the famine only lasted two years.

Genesis 47:13. And there was no food in all the land, for the famine was very severe, so that the land of Egypt and all the land of Canaan fainted by reason of the famine. 14. And Joseph gathered up all the money that was found in the land of Egypt and in the land of Canaan, for the grain which they bought, and Joseph brought the money into Pharaoh’s house. 15. And when money failed in the land of Egypt and in the land of Canaan, all the Egyptians came to Joseph and said, “Give us food, for why should we die in your presence? For the money has been spent.” Genesis 16. And Joseph said, “Give your livestock and I will give you grain for your livestock, if money fails.” 17. And they brought their livestock to Joseph and Joseph gave them food in exchange for horses and for the flocks and for the cattle of the herds and for the donkeys, and he fed them with bread for all their livestock for that year. 18. When that year was ended they came to him the second year and said to him, “We will not hide it from my lord, how that our money is spent. My lord also has our livestock, there is not anything left in the sight of my lord, but our bodies and our lands. 19. Why will we die before your eyes, both we and our land? Buy us and our land for bread and we and our land will be servants to Pharaoh, and give us seed so we may live and not die, so that the land would not be desolate.” 20. And Joseph bought all the land of Egypt for Pharaoh, for the Egyptians sold each man’s field because the famine prevailed over them: so the land became Pharaoh’s. 21. And as for the people, he removed them to cities from one end of the borders of Egypt even to the other end of it. 22. Only he did not buy the land of the priests, for the priests had a portion assigned them by Pharaoh, and ate their portion which Pharaoh gave them, so they did not sell their lands.
