I'm a theist because the idea of Nothing exploding with a bang (of whatever size) is unscientific. This notion of "First there was Nothing - then it exploded," imposes a greater strain on my credulity than anything found in the Book of Genesis. As does the absurd notion that human personality (mind, emotions, will) was once latent in a cloud or a puddle.
I suggest that a safer clue as to our place in the scheme of things may be found in the words of Samuel Johnson. Touching on the wisdom of Socrates, he commented: "The innovators [scientists] whom I oppose seem to think we are placed here to watch the growth of plants or the motions of stars. Socrates was rather of the opinion that what we had to learn was how to do good and avoid evil."
