But in school, they do teach the evolutionary theory. It's called that. At least it was at my school.
There's also the fact that if a child is religious, they get taught the religious belief of creationism or whatever it's called in Sunday school or whatever. So they're getting both sides of it, just not in the same place.
Oh, and just because someone believes in evolution doesn't mean they don't believe in god.

It just means they don't believe everything in the bible... or wherever the whole creationalist thingamabob is written.
I clearly know zip about religious beliefs.

But you get what I'm saying, I hope.
