“CAIRO Remains of about 50 mummies, including NEWBORN BABIES, thought to belong to the 18th Dynasty were found in a huge tomb in Egypt’s Valley of the Kings...”
4 And Moses said, Thus saith the Lord, About midnight will I go out into the midst of Egypt:
5 and all the first-born in the land of Egypt shall die, from the first-born of Pharaoh that sitteth upon his throne, even unto the first-born of the maid-servant that is behind the mill; and all the first-born of cattle.
6 And there shall be a great cry throughout all the land of Egypt, such as there hath not been, nor shall be any more.
29 And it came to pass at midnight, that the Lord smote all the first-born in the land of Egypt, from the first-born of Pharaoh that sat on his throne unto the first-born of the captive that was in the dungeon; and all the first-born of cattle.
30 And Pharaoh rose up in the night, he, and all his servants, and all the Egyptians; and there was a great cry in Egypt, for there was not a house where there was not one dead.
The Exodus was centuries earlier than this tomb.
