The big difference between science and religion is that science doesn't claim to have all the answers. In fact, if science had all the answers we wouldn't have science.You believe that matter came into existance from nothing then?
The fact that there is a universe is undeniable proof that matter was created at one point. There is only one theory as to how that could have happened. Choosing not to believe the theory is fine, but to state unequivocally that it is wrong, with ZERO ability to counter seems a bit early to me.
To state unequivocally that the creation theory is right simply because it's the only option is intellectually wrong.
