While not being much of a philosopher, the concept of infinity always smelled fishy to me, and never believed it was actually possible, even when I believed in an infinite God. Sure, I mostly excused God from deep logical scrutiny, but even then His omni-qualities raised some perplexing questions.
I would say now that God is impossible because infinity is impossible. The only realm where infinity can function is the abstract realm of human imagination. Same as God, basically 🙂
The following video raises the same problem, albeit with a more sophisticated approach.
