National Geographic Society has a presentation on Ancient Egypt. It confirms that Egypt was in its Zenith at the time of the alleged Exodus.
Because it rather lengthy, I'll highlight the important parts here:
"Egyptians wrote extensively, in their distinctive hieroglyphs, and practiced detailed art that depicted many scenes of Egyptian life.""Because they left such a rich legacy, the Egyptians are more familiar to us than perhaps any other ancient civilization."
(Wrote extensively... means we know what happened back then)
("Detailed art ... many scenes of Egyptian life" yet none depicts any of the 10 plagues)
(This is real stuff - etched in stone and tomb drawings)
"Throughout its history, ancient Egypt was dependent on the waters of the Nile to make life possible."
(These would be the waters that turned to blood...)
"Amosis drove out foreigh rulers and established the 18th dynasty at the dawn of the New Kingdom (1593-1075 B.C.). The kings of this era, including legendary rulers like the Ramessida Kings, reestablished Egypt's great power and wealth. The new kingdom represented Egypt at the height of its power, when pahraohs reigned from Syria to Sudan. "
(The kings of this era... reestablished Egypt's great power. The new kingdom represented Egypt at the height of its power." Now how could Egypt be at the height of its power after the events of the Exodus?)
"Wealth flowed from the Nile and precious metals emerged from the gold mines of Nubia to help build enduring monuments to the mighty pharaohs of the age."
("Wealth flowed....Well, the loss of 1/3 of the population, all their crops, all their cattle, the water of the Nile, all their slaves, lice, boils, locusts, etc... didn't stop them at all. Amazing.)
Can you honestly say that you believe Egypt could have been at the height of its power if it had experienced gawd's 10 plagues?
