As a laid-back atheist from way back, and non- scientific person too, it seems that there there could possibly be a 'something' at the end of infinity, if infinity has an end, which it is supposed not to do! What you call it is up to you I think. I just won't call it god. Or maybe in the end all existence morphs into the start of the eternal reality of the arsenic eaters of the extended universe.

Who knows?

Of course it is the uncertainty that makes pondering possible!
