A) Everything comes from nothing
B) Everything comes from something
Dedicated atheists will tell you that A is positively correct and they might try and take you back to some big bang which still needed some sort of fuel to happen. Even a spontaneous chemical reaction requires explaining as to where that gaseous cloud originated.
The reason I pick B is because it is the more logical of the two statements. After all, every process we observe in the universe has a beginning and an end; whether that be the creation of a baby, a rose or a diamond. It is what observe everyday in nature.
The additional problem with option A is that it hinges on the presumption that as limited flesh and bones creatures, additionally saddled with massive biases and blinders, we can comprehend the vast intelligence behind creation. This is not possible because our brains (sophisticated though they may be) cannot come to a resolution on such a hugely complex undertaking. Hence the only possible logical position left is agnosticism; i.e. to harbour doubt until things can be proven or disproven.
The fact is that the existence of God cannot be proven or disproven and to state otherwise is to be disingenuous. However, I prefer to observe that what I see all around me involves vast intelligence. Call it intelligent design if you will by some force or entity I cannot explain or conceive of.
As for the intelligence of some so called "religious" people, well that is another matter altogether.
