- The fine-tuning of the universe is due to either physical necessity, chance, or design.
- It is not due to physical necessity or chance.
- Therefore, it is due to design.
The universe is so finely-tuned for the existence of life that theories of necessity or chance as an explanation are highly implausible. The fact of the fine-tuning of the universe is almost universally accepted by those in the scientific community. The debate is on how to account for it. |

Hi!
We have a problem with assertion 2 here. The main issue is selection bias; I agree that the universe arising from pure chance *feels* very very unlikely -- the problem is, we have nothing to compare it against. So we actually have no way to judge the likelihood of this happening. And furthermore, if we assume that something preceded this universe, it's not a stretch to posit that other universes have existed prior to ours -- so we have no way of knowing whether there have been failed (or at least inferior) universes prior to ours. What we know about life on earth indicates that nature keeps throwing things at the wall until something sticks. There's no reason to doubt that doesn't happen on a larger scale.

Er, no reason to doubt that DOES happen on a larger scale.

This is the Many Worlds or Multiverse hypothesis which has become the focus of atheist scientists because they can’t deny the fact of fine-tuning. But it is an extravagant speculation with no evidence. To get around the obvious inference of intelligence from the unfathomable unlikelihood that all these precisely defined constants and quantities could have come together by chance, we are asked to believe that there are actually an infinite number of universes and ours just happens to be the one fitted for life.
Furthermore, we would still need an explanation for what generated all these universes.
Is it possible that there are innumerable universes and ours is finely-tuned by chance? Anything’s possible. You might actually be a brain in a vat being stimulated by a mad scientist to believe you’re reading this right now. The question is, which explanation is more plausible.
We DO have a “way to judge the likelihood” of multiple features of the universe being tuned to values which if altered by one part in 10100 or one in 10120 or one in 1010(123) would make the universe life-prohibiting happening by chance. Our experience and evidence tell us that is extremely, incomprehensibly unlikely. When coupled with the lack of evidence for a multiverse and a plausible model to explain it, the most rational explanation is design.

Wait, suddenly we're allowed to rely on "experience and evidence"?

What do you mean by that?
