Mixing theology and science
So if God existed and then "created" the universe where was he? In a void? How long was he there? Is there anything else God did?
If he, "God", has always existed, some form of universe has always existed too. It is impossible to go from nothing to something and so he really didn't need to create the universe because some sort of universe was already in existence, because HE existed.
So he was not really a creator, but a manipulator of existing energy. If you have any doubts we need only return to the bible, "God's word."
" And on the seventh day God ended his work which He had made; and he rested on the seventh day from all his work which He had made. And God blessed the seventh day, and sanctified it; because that in it he had rested from all his work which God created and made" (Gen. 2:2-3).
If God had to expend energy to create the universe (and since he is said to have worked and to have rested on the seventh day we must assume he did expend energy) then we have further proof that God is not a creator but rather a manipulator of existing energy.
No one asks those questions in church. Asking questions isn't expected. Religion demands subserviance to a set of preconfigured ideas and rules. Logic and reason are not welcome bunkmates of theology.
You're mixing theology and science. "God did it" was a fine line back around 1480 when few could think there way out of the logical fallacies inherent in the concept of 'creation', and had to fear being tortured or worse for speaking out in defiance of them, but nowadays you'll find a good number of folks who think that line is a poor relic from a pagan era reiterated ad nauseum to folks who can't (or don't want to) think.
All things point to an infinite universe.
And once one realizes the universe is infinite, he/she no longer seeks the answers to "creation" or other unscientific conceptualizations but observes the tangible.
The tangible evidence around us shows energy merely changes form and can't be created or destroyed. Science must pursue and map the tangible and observable. These changes in energy form and how such changes work are the goal of science. The fantasy and pursuit of 'creation' should be left for theologians.
