Mythbusters: The Bible

[Patriarch of Constantinople]

The Plagues cast down by god onto Egypt:

rivers and other water sources turned to blood
well red sands from ethiopia and other mid african areas were drawn into the nile, creating a blood colored river

reptiles (commonly believed to be frogs)
easy, as the river filled up with the red dirt, the insects and fish started to die. the insects moved out, not giving the frogs a source of food, so they moved out.

lice
same as above (without the frogs)

'Arov', meaning either flies, wild animals or beetles
this was a plague that destroyed livestock. another easy one to explain, the insects moved out the of the nile, carrying disease that affected livestock.

Pestilence
see above

Boils
insects

Storm (fiery hail)
my best guess would be volcanos

Locusts
same as frogs and lice and Arov

Darkness
now this has two possibilities.
1. volcanos (fiery hail) ash blocked the sun
2. the locusts came in huge crowds and swarms blocking out the sun

Death of Firstborn
now this one is unexplainable. my best guess is disease from cattle and insects. the hebrew first born were protected because they moved out of the area.

as for the walking on water, i doubt judea snowed

[The Stranger]

i just read an interesting piece about this in the yesterdays newspaper... ill post it as soon as possible

[Glaucus]

About Jesus walking on water... I've always had a sneaking suspicion it had something to do with the salt content in the Dead Sea. Maybe he just floated in the water, and the story got magnified by many people telling it over and over. I don't know the story that well so I can't really pass jugement... I'm a Jew
