Thus far, I've only stressed two points, which should be obvious and non-controversial:
actually, both of your two points are controversial in the extreme.
1) "Fine-tuning" is real. If a number of fundamental constants/laws of nature (notably the cosmological constant) were not fine-tuned to an incredible precision, life could not exist in the universe. Not just "life as we know it," but any sort of complex life at all.
That is, I believe, "confirmation bias"? Sorry, I don't know the terms.
You confuse the fact that life as we know
is as we know it, with the universe being as it is
specifically for life as we know it to be "life as we know it".
We're here - correct. The universe' make-up allows us to be here - correct. The "fact" that the universe was specifically
fine tuned to be as it is? I don't think you can go that far.
Saying it is "fine tuned" implies that somebody or something did the fine-tuning. Saying it's fine-tuned implies it's not possible for it to happen "naturally".
I don't think your universe or multiverse creation skills are that good you can pronounce such a thing as quantified.
2) This fine tuning begs the question of "why?" It is certainly true that if the universe did not have the fine-tuning that it does, we would not be here. But this ducks the question of "why" rather than answering it.
no, there you're wrong too. It is not certainly true that the universe was fine-tuned - it's true that it is the way it is, but you haven't proven fine-tuning.
It's true that if things were different, we'd have a very different universe, but that's besides the point.
If we knew more about the universe, or the multiverse, and could say without a doubt that it is extremely unlikely for a universe like ours to exist...you'd still not have definitive proof of "fine tuning".
You'd have to either prove it impossible or find proof it was deliberately shaped.
