I was just having a think about the evolution/creationism argument......?

.... and although personally in all for the evolution argument, I can accept that although there is no evidence for a God existing, there is no evidence against it. The thing I find myself thinking about the most is where exactly did the first atom or particle or whatever you want to call it come from??? I mean it actually hurts my brain to even try and think about the origin of the universe! And for those religeous people out there.... where the heck did God originate from? Seriously its actually quite scary thinking about the fact that was have no idea where we or anything actually came from. Also, what happens when you reach the end of the universe? Or does it even have an end?!?!?!?!? haha sorry rant over!
