A fined tuned argument.....Heywood style.

[Heywood]

Ok, you just systematically removed your hypothesis from testability because you proclaim that it does not make any predictions as to how the universe looks, and you think this somehow strengthens your hypothesis, but it doesn't. If hypothesis A makes no prediction for a certain observation, but hypothesis B does, and observations match the predictions of hypothesis B, then B is to be favored over A at least with respect to these data.

Since the multiverse hypothesis can explain anything....it really explains nothing.

We're back to having no reason to favor B over A other than subjective ones. Indifference is at least objective.
