There seems to be a real problem with the word appearance and what that means in regard to the fine tuning problem in astrophysics. There are only a few astrophysicists that deny fine tuning and that the values of the universe are those required for life on earth.
I don't think anybody denies THAT!
Yes, to have life on earth (or to have earth in the first place) the universe can't be any different than what it is now! I agree! No argument there!
I disagree with the assertions that:
1. No other possible configurations could lead to a universe where life or something like life can exist.
2. That there are other ways the universe even could have been, which is important, otherwise you wouldn't need a fine-tuner in the first place.
3. That there is something "special" about this universe just because it has life in it.
The fine-tune-argument depends on all three of them! And none of them can be demonstrated to be valide!
I'm not saying that they are FALSE, I'm saying it's a baseless assertion, that they are valide.
It is not like a few scientists "see" design where others do not.
Ohhh, they most certainly do!
There is NO consensus among the scientists in those fields, that the universe is designed! The people who claim it is are actually a minority!
And this doesn't even depend on your previous argument, with which I disagree!
I could now grant you completly, that not only that we need exactly these parameters of the universe to have life, I grant you that there are literally no other possible ways it could be any different (these points haven't shown to be valide, but who cares... I grant you that just for the sake of it)...
You STILL haven't shown design!
You have shown that the configuration of this universe needs an explanation.
But to show design, you need to show a mechanism by which it was designed. You need to show that the design-process is at least POSSIBLE... let alone probable!
So yes: The people who claim that this universe is "designed", they just see design, where they want!
I'm not saying that there is no design, I'm saying that there is no support to say that it IS designed.
It comes down to the data, what that data means in regard to what we know about the Laws of Physics, the requirements for life to exist and how finely those values are tuned to fit those requirements.
And what life did you use as standard?
Well... this one on earth, right? Because it's the only one we have!
And so we are back to that: Yes, to have earth and life as we know it on earth, we need to have EXACTLY this universe! Big deal!
