There is a distinct difference between atheists and agnostics.
Atheists beleive that there is no God or higher power controling the universe.
Agnostics are undecided on the matter (I.E. There may be a God, but there may not be.)
Also, I've got an Agnostic friend, and he really hates both sides of the argument. He told me to say that neither of us have any room to consider the other's arguments.
So i'm considering.
It is also thought amongst radical christian circles that God may have used evolution as a way to create the life on the planet. It is also generally agreed that there was something before the big bang. Most christians believe the big bang was a result of God saying 'Let there be light'. I agree, it was probably a very large noise when God spoke.
I dissagree with this. A theory is simply a Hypothesis that has been generally accepted by the scientific community as a possible way of thinking about a particular problem. Also, there has been no conclusive evidence that suggests anything on this earth has been a product of evolution.

there are many more links (just google it) with evidence on both sides. But it cannot be ignored that there is no fundamental scientific proof the evolution is the way that life on this planet originated.
