God has no beginning nor ending. He created us all thats all i know. If theres a building, theres a builder. Who created the universe? Where the humans came from? Scientist cant prove that. They just created theories and make themselves believe it was happened. No one can see God coz he is a spirit(no flesh and no bones). But we can see Him through the things He created.
You say scientists just created theories and make themselves believe it but arent you just doing the same with your god?
At least scientist forever strive to validate their theories through provable evidence. Gods just remain a blind faith.
