exactly, except for one thing
we assume that something can't come from nothing. we need to realize that no matter how much we catalogue "the rules of the universe" in physics, math, etc, there is always room for error. Something so absurd as the explosion of the universe outward from anything could possibly have completely different physics. Theres an infinite number of ways that the creation of the universe could be explained, which makes it seem all the dumber to see people who think they have everything figured out beyond a shadow of a doubt
