Even though you are from north America and you don't have much time, i will try to help you.
At that time there was not the Moon in the sky, the gravity was great and so the people were huge and they lived many times what we do.
The Sun was cooler and much of the water was retreated to the poles as ice exposing much more land than we see today and a big inhabited island in the middle of the Atlantic.
haha LOL
