Excuse me, Unknown, but though I don't go along with the ridiculous story of Noah and the flood, you are completely wrong when you talk about the death zone Noah would have found himself in.
You see, the rising sea level would push up the Earth's atmosphere along with the ark so the thickness and temperature of the surrounding air would be similar to that at normal sea level. It would still be hotter at the equator and colder at the poles.
Just thought you'd like to know.
