Because a gift that is demanded is no gift at all.
As far as being all-knowing contradicting free will... Not sure how you're reaching that. For example: Just because I knew you were going to buy that Sentra three weeks before even you did, didn't stop you from buying it, did it?
Who said anything about being alone in the universe? To take a quote from the horrid Jody Foster movie Contact... "I'd say if it is just us... seems like an awful waste of space."
But anyway, I'm not going to post in here anymore. The thread is about do you believe or not, yes or no. Debating it is pointless.
