Does God Really Exist???

When I was young I had an experience which proved beyond any doubt that "God" is indeed a very real person. If the big bang theory is correct then God must have evolved. I can theorize with the best and rest of us but where is the evidence that there exists another planet with pre-sapien spirit hominids. God is a spirit. Were his ancestors spirits. Or did flesh evolve into spirit? If any of you saw what I've seen there would be no question at all "Does God exist?". There really are people in the universe who look just like us and live for thousands of years at the least, without any doubt. I have a question as well... How do the stars keep lit with flame if there is no oxygen in space? I am aware it is possible to start with 1 thing which produces enough of it's own fuel to make 2 of itself without extinguishing the first. This would mean though that there are stars which will burn forever. I am sure there are particles which aren't made of smaller particles. These stable particles don't break down at all even literally forever. It is wise to hypothesize yourself as one of these, anything less is a bit futile. I am sure there is a particle which is stable and doesn't break down and this is the basis for all other particles. If something were to travel faster than light would it be by nature invisible...if even for a while? If...if...hmmm.
