That's why everyone's retarded.
Seriously, I'm partially joking.
The whole Adam and Eve story is actually just figurative for the way man desired eternal life but was too impatient to search for it.
Instead, he ate from the tree that grew fruit that contained the knowledge of good and evil (The Knowledge of the Gods).
Once this was done, Adam "thought" that he was a God, and therefore had the right to dominate Planet Earth and all of its beings.
There are many other stories in The Bible that relate to something that actually happened in the world at one time or other.
But really, if you want to ask a great question, ask,"Why the hell is dominating Planet Earth and all of the species on it (excluding man) part of a religion?"
It gets you going much more than if you ask yourself,"Hyuck-hyuck why did Cain sleep with his sister??"
Sorry, I edited my previous message and it took me five minutes, which was obviously devoured by three posts.
