Of course you can have any sort of fantasies you like about there having been other universes and other times and spaces. This is only natural for a writer of fanciful fiction. We on the other hand are going by the facts we know.-First a quick comment on where dhw takes you task on (that's how it read to me) on using an if statement. I disagree with dhw, here ... it is the agnostic thing to do and we can follow the logic and consequences of where an if statement leads us. So I am not sure why dhw would even bring it up.-But the facts we know, I might have worded differently ... I probably would have written something like We on the other hand are going by the data and models we have.
