God was never born, has no children, no parents, knows all, needs nothing and no one.
He created every thing from literally nothing as science can prove it already.
Can you imagine that the whole universe out of no where and from nothing first started just to be and still continues to be?
While time and space are one but at the same time two things, where gravity is heavy time passes differently, just like near black holes, or if you move faster like speed of light again time passes differently.
But imagine a movie where you can skip to any time, go forward or backward, with God it's like that he has access to the video tape if you may call it and it doesn't affect him at all time never passes for him.
Can you imagine beyond our universe? if you first can find any edge for it then anything there again imagine the plain of existent beyond that and to what extend could you go worlds beyond worlds? you will be going for billions of years and still unable to reach the end of our universe and when you get there then ask your self this question.
God is everything that could be out there or any where, very simple he is everything that could be.
Also have you seen "Ancient Aliens" ? they were all sent by God to do what he ordered them to do, how ever some of them saw some candy and wanted some then got kicked out of the club. they were naughty.
I personally believe that heaven and hell are in fact in this same universe of ours.
There is evidence in the Bible that suggests both things. Heaven and Hell are in this universe, and Hell is this universe while Heaven is an entirely new universe.
Personally, I get the idea of a whole new universe from the way I see the last few chapters in the Revelation. After all, this earth is imperfect. Some of that imperfection must travel out to the universe from the light that is reflected off the earth. So, the whole universe is receiving imperfection from earth. But Heaven will have no imperfection.
Jesus has corrected things, of course. But we don't see the perfection here. Does He have a way of filtering the light as it leaves the earth, so it isn't imperfect anymore? Perhaps. But Saint Paul says in at least two places that the devil is in the air... one place even calling him the Prince of the Power of the Air.
Whatever is done at the end, there will be no more imperfection for any who go to Heaven.
