Egyptian Creation Myth

Here is the link to the website where I found the Egyptian Creation myth that I presented (Atem).  You have to scroll down quite a bit to get to the actual myth but the introduction is interesting too.

As we discussed in class a majority of the creation myths were of the Earth Diver category.  In it the world is all water and an animal dives down to the bottom and brings some earth up with him/her, which is then molded into the world.  This has made me curious as to whether a majority of cultures in the world feature Earth Divers in their creation myths or if the class is just biased towards those types of cultures?  It also made me interested in whether the animal that finally brought up the earth, was revered or considered sacred in the culture or not?  If it was revered do the cultures still find it revered today or what?
