But it's not rationale. You're assuming it only because we do not yet understand it. At best it's a filler-answer, at worst it's an imperative to simply stop looking for the actual answer.
It's because we do understand it, we understand that there WAS a beginning, a specific creation event- not a static uncreated universe as atheists predicted.
we understand the Galaxy is NOT teaming with other sentient life, but that we so far appear to be alone
we understand that the probability of happening upon the universal constants by chance are so staggeringly low, that it would require a practically infinite imaginary multiverse to fluke this one.
