Do you believe that something
can come from nothing?
It would appear, if you are an atheist, that you do so.
In a sense. I believe that new concepts and ideas come from “nothing”. There is no causative precursor to Beethoven’s Ninth Symphony. It was not “caused” in any sense of the word. It was created by Beethoven “ex nihilo”. Every genuinely “free action” is uncaused (otherwise it would not be “free”). So uncaused actions are “dime a dozen”.
But that is NOT the question at hand. Your assertion seemed to be that atheists believe that the universe “magically appeared” out of nothing. This “picture” has many problematic aspects. First, it treats “nothing” as an objective, ontological entity, rather than a concept.
“Nothing” does not exist, except as a concept. So the assertion: “something came out of nothing” is a nonsensical proposition.
Next, the atheist view is that the universe is an existential primary, it is the foundation of every explanation. Explanations can only appear within the universe. There is no space, no time, no causation OUTSIDE the universe. This whole “imaginary” problem of “something came out of nothing” is just a leftover from the old and obsolete Newtonian worldview, which “imagined” the universe as a “bubble” of something drifting in the space of nothing and this drifting happens in the absolute space and time.
This worldview has been made obsolete by Einstein’s general relativity. There is no “absolute” space or time. Space and time are the attributes of the universe. So, to answer your question, the atheist view is that the universe
simply exists. It exists necessarily, it cannot not-exist. Since this is exactly your view about your God, this approach should not be surprising. There is of course one major difference. The universe DOES exist, of that there can be no doubt. Its existence is empirically established. The same cannot be said about God.
If you believe that God exists, that is your business. The problem is that God’s existence has no explanatory value. The “God said: let there be light and there was light” explains nothing. So instead of having one unexplained starting point (the universe simply exists) you have two points: “God simply exists” and he “magically created the universe” by waving his imaginary hand. And that IS really “magical”.
