Many years ago, I woke up in the middle of the night with absolute proof of God's existence. I went back to sleep and woke the next morning remembering that I had proof, but not remembering what the proof was.
Being the agnostic that I am, I have to move forward without any belief in anything and disregard the memory.
If God wants me to believe, they have to resubmit their proof of existence.
Maybe in writing. In triplicate.
