One question: What blew up (Big Bang)? For this theory to work, you either choose to believe in eternal matter (that stuff that blew up and we all "evolved from" to begin with) or an Eternal God. Therefore, evolution is a "Belief System." Like it or not, you have to take a step of faith in one direction or the other to believe in the THEORY of evolution, either way, faith and belief are still a requirement.
