People are, without exception, terrible at scale.
Consider, if you will, the Universe. Since you are terrible at scale, you obviously can't, so let's try again. :p
Consider, if you will, a largish field which is infested with ants. Imagine that, for some reason, you select a particular anthill to be special. But this is not nearly specific enough. Imagine that then, you pick up a particular ant, and let it run around blindly on your hand. Since you'd like to see it a bit closer, you set that ant under a microscope. You see a single cell which particularly strikes your fancy, so you zoom in on that. You are so taken with this one cell on this one ant, that you spend all your time examining it, and eventually, you become acquainted with its very atoms. You decide then that you will grant the wishes of these atoms; but only the carbon atoms, we wouldn't want to be too generous, now.
You would agree, I'm sure, that the above is a fairly ludicrous example; unfortunately, I fear that I've underestimated the scale, if anything. And yet, this is what every theistic religion would have us believe. The idea of a creator, I have no problem with - a creator can't be proven or disproven, so there's no reason to dismiss the possibility. But to think that, after creating the entire Universe, a being that powerful would then look at me, a speck living on a speck orbiting a speck on the arm of a not-especially-impressive galaxy, for even a femtosecond, well, that would be more than I could stand.
If you want, you can believe in a God who meddles in the lives of atoms jostling around on an ant's back. I won't try to stop you; I won't even disagree with you. My Universe is a cold, lonely, and sensible place, though, and that's the way I prefer it.
