You do not take other peoples ideas seriously because you feel safer where you are and that is deeply into empiricist and naturalistic philosophy.
You need to ask for a refund from your mind-reading course.
To me there are 3 possible reasons for the universe personal creator, infinite universe, spontaneous appearance. To dismiss( an act in itself) the first can only be achieved by mental contortion.
I've already explained firstly, why your list does not contain all the possibilities, and secondly, why speculation about a "personal creator" doesn't actually address the problem of existence at all and is therefore nothing but a pointless guess.
I have no idea why something exists rather than nothing, or something entirely different, but guessing about a creator doesn't address the problem. Therefore you have failed to give a sound reason to take your guess seriously. For clarity, I'm not saying it's
impossible, just that it's an unjustified guess.
