I was recently introduced to Eric in a r/DebateAChristian thread. Here’s how Eric is defined [on https://ericthegodeatingpenguin.com/]:
God can’t exist because of Eric The God-Eating Magic Penguin. Since Eric is God-Eating by definition, he has no choice but to eat God. So, if God exists, He automatically ceases to exist as a result of being eaten. Unless you can prove that Eric doesn’t exist, God doesn’t exist. Even if you can prove that Eric doesn’t exist, that same proof will also be applicable to God. There are only two possibilities – either you can prove that Eric doesn’t exist or you can’t – in both cases it logically follows that God doesn’t exist.
The issue is that for Eric to be able to ‘eat God’ he would be greater than God. Which naturally makes Eric God. So whatever Eric ate wasn’t God, and God still exists, his name is only Eric.
Of course, there are no reasons to believe that Eric exists. But even if there were, God could still exist. God would still exist.
