Contemplation of the existence of God, or infinity, or eternity, or a singularity, or what-came-first, is useful anly as an excersise in mental agility. It will not provide any answers. If God does exist, for reasons apparent only to himself, he has decided not to reveal himself to us. An omnipotent omniscient God is clearly clever enough to keep himself hidden if that's what he wants, so I doubt if you are going to find evidence of his existance. Similarly, if he doesn't exist, neither will you find conclusive evidence of his non-existence. Queer, eh?

You, like everyone else, have to supply your own compelling reason.
