Something from nothing is impossible because ‘nothing’ has no properties. It cannot cause anything, it cannot change, it cannot act. By ‘nothing’ I mean the absence of anything, not empty space or a vacuum. You cannot test it because there is literally nothing to test. As for believing in something eternal, it is not about humility but about necessity. If the universe began, something beyond it had to cause it, and that cause has to be eternal by definition. Regarding God acting, an eternal being can will to create without being bound by time, and the moment He creates is the moment time begins. That is not just giving a name to ignorance, it is following the evidence to the kind of cause that fits the effect we see.
