Big Bang... or not?

I'm one of the first people to jump in line and say that everyone has a right to believe in what they want to believe in, but sometimes, the stupidity of people amazes me.  I know there are plenty of people (even people I love and respect their opinions) who disagree with certain controversial science.  Such as certain parts of Evolution (normally the "monkey to man" part of it), or the Big Bang, though many religious people take the "And God said 'let there be light'" part of the Bible as a possible metaphor for the Big Bang.  But to just outright say "There was no Big Bang. Period. God created the world in 7 days, end of story," is just plain ignorant.

If you don't really believe the Big Bang happened, that's your deal, I don't really care.  But when you start insulting other people because they believe a widely accepted scientific theory on the beginnings of the universe, you're going beyond not believing at that point.  Religion and the people who follow it amaze me anyway.

All you have to do is look at the past.  Just take a look at how Christianity has handled new scientific discoveries in the past (such as Earth being the center of the universe, or the earth being flat, etc.) and how unbelievably wrong they were.  Yet people still cling to the old views of their religion instead of paying attention to the scientific evidence.  I just don't get it.
