Considering God is omnipotent, and for that reason alone he can never be disproved, it's only fair to say that belief in God is nothing more than a choice.
Is there someone in the sky watching over us? Maybe, maybe not. But if someone was in the sky watching over you, guiding and protecting you-- would that bring you comfort and happiness?
Or does it bother you that, if God exists, that we wouldn't be the masters of our own destiny, that the belief that some people have of a God is only blinding them and preventing humanity as a race from evolving?
But it's a choice. Each and every one of us defines our own reality. It doesn't matter if someone else's science says that God probably doesn't exist, nor does it matter if someone says God absolutely must exist, it only matters what you decide, because when it comes down to it, reality is the most precarious of all supposed truths, considering people don't even question it's flaws.
We may have just started existing an hour ago, and everything we think we know is just implanted memories.
Or you may be the only person that really exists, and everyone else is just a projection of your subconscious.
Or every single one of our thoughts was predetermined, like a script.
But those are all outrageous possibilities, but possibilities none-the-less because they can't be proven false.
So you can choose to believe any of those or anything else you'd want to.
So the question is: Do you want there to be a God?
And your answer to that question is the truth.
