This is a thought I've had before, and I'll likely have it again, because I don't think that anyone knows the answer.
Why did God create humans? Or, really, anything at all, but specifically, people. Knowing how it would all go down, why bother?
p.s. I've gotten the answer, before, 'so we could worship Him'. I find this answer unacceptable, because we're still left with why. Why did God create us to worship Him? Does He require our worship for some reason? If so, He's not self-sustaining, and therefore, not God, but a god. So.
