Sorry for the slow reply. We lost Internet most of yesterday.
That's exactly what he implied. How could you not see that? If there no true" therefore God" statement, only atheists have sound minds obviously.
You're confusing unsound conclusion with unsound mind.
Consider your list of candidate hypotheses for the the history of the universe, which had only one element: God. Mine looked like the following. How did you get from mine to yours? You either never considered several of these logical possibilities, or else you dropped them for no reason valid reason:
The universe:
I. Had no prior cause
1. Always existed
2. Arose uncaused from nothing
II. Had a source
1. Unconscious substance (multiverse)
2. Conscious (deity)
The first two are ridiculous and go against all scientific laws... So we can toss those. The first second one is equally ridiculous as it has no evidence whatsoever, and explains nothing about anything So we are left with God.
OK. So, it was the latter - you those possibilities dropped them for no logical reason. That is exactly how you come to unsound conclusions. It's easy. Just include one or more fallacies in your reasoning.
As I suggested, there is no rational argument that ends, "therefore God." You're argument ends that way, but it is unsound, flawed, fallacious, irrational. You're fallacy is argumentum ad lapidem, or simply dismissing a logical possibility with a wave of the hand and the utterance of the word "absurd." Allow me to demonstrate:
The universe:
I. Had no prior cause
1. Always existed
2. Arose uncaused from nothing
II. Had a source
1. Unconscious substance (multiverse)
2. Conscious (deity)
The last one is ridiculous. Just drop it. We are now down to:
The universe:
I. Had no prior cause
1. Always existed
2. Arose uncaused from nothing
II. Had a source
1. Unconscious substance (multiverse)
With that step, my conclusion went from sound to unsound (to irrational), although I did not not go from sane to insane. You did the same, but rejected different logical possibilities without cause. Your response became irrational.
But you're not alone. This is the same error Craig makes in his Kalam argument. Somehow, the multiverse never appeared on his list and was never ruled out, either. His argument ends with, "the universe had a cause, therefore God," but not before adding a bunch of features to this god without support.
Here it is to remind you:
William Lane Craig and the Kalam Cosmological Argument for God:
1. “Whatever begins to exist has a cause of its existence.”
2. “The universe began to exist.”
3. “Therefore, the universe has a cause of its existence.”
4. “If the universe has a cause of its existence, then an uncaused, personal Creator of the universe exists, who sans creation is beginningless, changeless, immaterial, timeless, spaceless, and enormously powerful and intelligent.”
5. “Therefore, an uncaused, personal Creator of the universe exists, who sans creation is “beginningless,” changeless, immaterial, timeless, spaceless, and enormously powerful and intelligent.”
You haven't refuted the claim that if a deity can exist uncreated and with no beginning, then so can a universe or a multiverse.
The claim in the Christian bible is that when this world is ended there is heaven. The description in Revelations states there is no more earth (it has fled away) and no more sea, no more time and no more sun. Essentially an existence without a universe. We can refer to this idea as
1 - inside, ie the universe of stars, space, physics - everything natural
2 - outside, a putative 'place' beyond the physical realm which existed before and after the universe existed. Not even the number zero exists.
This is pure belief in the bible. So this is a realm for which nothing is known. I fully understand how you take this - I am a science fan, all my life, and was a science teacher too. I have long enjoyed challenging people who hate science, everyone from anti-vaxers to creationists. When I put ideas forward regards first creation account in
Genesis 1 I find it creeps everyone out. I call these the 'orphan verses' because they disturb creationists, ie 'God commanded the seas to bring forth life' and the same verses freak out the secularists who hold the bible is mythic.
That still doesn't refute the claim. We reached the end of this discussion the first chance you had to rebut and chose not to. Correct statements cannot be rebutted, which is the likely reason you don't try. I consider the matter resolved. All debates end with the last, unrebutted, plausible statement, which in this case, is one I made that you keep deflecting from.
