This may be an old argument, but I just ran across it on a random podcast:
One argument for the lack of clear evidence of God is that it would undermine free will: anyone who knew for a fact that God exists would be overcome with goodness or something, and in the presence of such a cosmic carrot, would effectively lose the ability to sin.
To this the counterargument is, what about Satan? Satan supposedly had direct proof of God, talked to him, met him at the workplace, and so forth. But he still rebelled.
One might retort that Satan was angelic, not human. But then either Satan had more free will than humans do (in which case one must wonder why God didn’t build humans the same way), or Satan had less free will, in which case the whole thing was a setup.
Discuss in the comments. Next week, we’ll address an equally weighty question: whether the Millennium Falcon can beat the Enterprise in a fight.
