I just watched a show on the National Geographic channel that talked about this.
Some archeologists in Egypt have found the body of the Pharaoh Rameses first born child.
Rameses is the Pharaoh that ruled Egypt during Moses's time.
According to the show, all of the plagues that God visited on Egypt can be explained by science, and are quite possible.
The only one they have trouble with is the killing of all the first born.
According to the show, Rameses first born was in his early 30's when he died, and he died from a blow to the head which crushed his skull.
And the parting of the red sea is, according to scholars, most likely a mistranslation.
The words actually mean reed sea, and that is a swampy, marshy area near the Nile delta.
It is quite possible that Israeli's fleeing Pharaoh, could have ambushed and destroyed Pharaohs chariots there, because chariots and swamps dont mix.
According to the bible, the slaves were building Pharaohs city, a city many people thought was a myth.
That city has been found. Its name is "Pi Rameses"

Also, according to the show, there is written record of a battle between the Israelites and the Egyptians, a battle the record says the Egyptians won.
The name of the show I am talking about is "Rameses, Wrath of God or Man"
It was on the NatGeo channel, and if you get a chance to see it, it was really interesting and informative.
They even postulated the idea that Moses was actually a son of Rameses, one that believed in the sun god Aten, a single deity that some Egyptians was the sole God.
