Although I am fully aware that common sense is not the best thing to use when we are talking about such complicated matters, I'd have to say that the answer to this fine-tuning issue is derived from common sense.
In case anybody was curious, this is what it looks like when someone abandons evidentiary argumentation and instead substitutes their own prejudices.
Before you start basing arguments on so-called "common sense", maybe you should stop and think about where common sense comes from, and why things that seem so "commonsensical" to you might seem outright wrong or dumb to another, like this:
Now, whether life is fine-tuned for this planet or this planet is fine-tuned for life on it is a messy issue, one that I am still trying put my fingers on.
Now, see, here's where my common sense wonders why you have a problem with this. When you see one thing that is malleable - life - and another that is not - the laws of physics, etc - it shouldn't be messy in the least to determine which shaped the other.
The cup shapes the water; the water does not shape the cup. Like I said, its common sense to me, but then, I don't go around substuting "common sense" for rigorous argumentation, like you seem to do.
Although this is a wide margin, in astronomical terms it is not so wide.
It's .8 AU wide - 8/10's as wide as the distance from the Earth to the Sun. And you think it's unlikely that a planet would form somewhere within that distance?
Just to put in in perspective, there's
two whole planets within .8 AU of the Sun.
So, surprise. Since life on Earth was shaped by the conditions it found itself in, if those conditions had been different, it turns out that life would wind up being shaped differently.
What a truly shocking revelation. You might be interested to know that if you pour water from a cup of one shape into a cup of another, the water
changes shape. Wow!
I'm sorry, was that sarcastic? My bad.
AbE: Ok, now I see that that actually
was my bad - no sarcasm this time. I see that I misinterpreted the tone of your post. I do apologize.
