Although this may seem difficult or even impossible, try to imagine what it might have been like before there was an Earth, before there was a universe. Then ask yourself, what was there before that? If you come up with an answer, accept it and ask, what was there before that? Keep going back until you can go back no further.
Now try the same exercise forward in time. What comes after this universe that we live in? What comes after that? Clear away whatever comes up and ask, what comes after that? Keep going until you come to a stop.
If you go back far enough, there are only two possible answers to this question; either there was nothing, absolutely nothing at all, or else this universe is eternal and had no beginning. Likewise, looking forward, either there will be nothing left, absolutely nothing at all, or else this universe is eternal and has no end.
If there was absolutely nothing, the question is where and how did the universe spring into existence? If there was absolutely nothing, there was no need to do anything and there were no resources to make it happen. Nothing would just continue to be nothing. The only power that could possibly create something from nothing is Consciousness.
Consciousness means: an awareness of self, environment, and mental activity, and the ability to determine choice of action. So, in saying that Consciousness is the only power that could create something from nothing, I am saying that awareness and an ability to determine choice of action were the prime qualities needed to precede the creation of something from nothing. Science has no credible explanation of how nothing could suddenly become something. Scientists start with the Big Bang, not before it.
Just as an idea might be created out of nothing (though this seldom happens), so conceivably a powerful enough Consciousness might create the universe out of nothing. So, if there was nothing at all, there at least had to be Consciousness existent in order to create the universe of which we are now part. Man has decided to call this Consciousness “God”.
The other possibility, that the universe is eternal, without beginning or end, also seems to imply some sort of eternal force that underlies the whole process. We know that nothing physical lasts forever, so there would need to be a non-physical force underlying the universe just to keep it maintained. This force is best described as “Consciousness” or “God”.
Now, if we look into the future, either things go on eternally or else there will suddenly be nothing. Where will everything go unless it is dissolved back into Consciousness (God)? If God switches off and dies, there will be absolutely nothing, and no chance of a new start. It is very unlikely that if God started out eternally (in our past), that He would not continue into the future eternally too. And if He didn’t, and there was absolutely nothing left, it wouldn’t matter, would it? So, if there is eternity, there has to be something that is eternal. That something is Consciousness or God.
Does God really exist? Of course He does! Our concept of who or what God is may be inaccurate. But there had to be something, Consciousness in fact, to pre-exist the Universe. We may as well call this pre-existing Consciousness God, because in essence that is what being God is all about.
