because there isn't any proof he exists, but there isn't any proof he DOESN'T exist either
As for me I hardly think so and the argument for an existing God is just as good (if not better) as what science proposes our origins came from.
I'll start off with the argument that God does
not exist. Most atheists believe that something (the universe) was created from nothing (or from some other mass) in the Big Bang and everything took billions of years to get the way it is today. The theory of life forming was through the formation of amino acids in the oceans (or through further unbelievable things like life arriving on earth by meteorite). However, we have never been able to create life as far as I know through our advanced methods of science, but somehow, it was supposed to happen multiple times over Earth's long history all by itself. It's apparently a very repetitive occurrence, especially since every time we find a planet similar to earth everyone suspects that life either was there or could exist.
The argument for God creating the universe is difficult to sum up in one paragraph. Just like the "scientific" (in quotes because many say Creationism doesn't apply science) version, everything was created from nothing. Although many creationists try to claim the Big Bang didn't happen, wouldn't the sudden creation of light in the phrase "Let there be light" seem like a Big Bang in a place only seen with total darkness? Both views also seem to claim that something was always existing in the time before everything was created, which means that the concept of time had no definite beginning. God is infinite with no beginning or end. Likewise, the mass before the Big Bang (if it existed) would've had to begin somewhere or else the concept of infinity still applies. If mass cannot be created or destroyed, it would either have to be created anyway or have always been there for an infinite amount of time before the Big Bang. For God creating life, assuming he created the universe, it would be totally possible. He created humans to be a companion for him in his likeness.
