Either the universe always existed, or it was created. If it was created, it was by a being outside of the universe.
“Something from nothing” is not possible.
“If it was created, it was by a being outside of the universe.”
And where did this magical being outside the universe come from? And what’s this thingy outside the universe?
I doubt very much we’ll ever know the answers to these questions. We’re caught in a catch 22 world.
We’re about as capable of knowing these things as an amoeba knowing what a human being, or a tree, is.
