[From many - one.]

A few concerns:

1. The reptile looks like a mammal to me. There's a difference in the way the legs are set.

2. The Tigris and Euphrates are two rivers and I didn't see a desrciption of a third riverbed.

3. Although we like to see grain agriculture as a good thing, I doubt it was seen that way back then. More a way of shifting to an efficient way of preventing starvation when the good stuff (fruits, meat) became hard to find in an increasingly overcrowded world.

Me too. Look at the rib cage and the way the eyes set in the head. I think it represents a dog.
