Spirit of Light
Be who ever you want
I do not know where the Gods first appear, but in my understanding, it was long before time known to man. ( in Buddhism it is said that Sakyamuni saw 81 universes before this current one) so that's a long time.Science is only hypothesising about the Big Bang's origins.
But your "...If there is no creator or God or intelligent being that put it in motion..." does not help because the next question is...
Where did your creator or god come from?
