*ding*Incorrect. It's taking what I know about science and believing what is plausible regarding something that no scientist has proven and can study. By your logic, is it not equally true for atheists to believe some kind of self propagation method for the creation of matter and energy?
Unfortunately science doesnt understand exactly how the universe came about, but you're still reverting to 'God' as an essential argument for things that are not explicable. Just because science doesnt know yet doesnt mean you need God to explain it.
