The conversation was more between Hawking and Schroeder. For me there is a lot of talk in Genesis about the
firmament or what we call the atmosphere. I just saw some photos taken from a weather balloon and the earth's atmosphere is very thin. So I do not know how much can be accomplished with the atmosphere and how much we need to duplicate the conditions we find here on earth. Even here on earth we seem to have a very narrow window of opportunity. When we do our gardening the conditions we need to provide for plants to prosper can be somewhat narrow. Weeds do real good all by themselves but a beautiful cultivated plant requires a lot more care then a weed. Schroeder attempts to address the issue of why the ground is cursed so that we have to fight with the weeds to cultivate our food. Very few people go into that dept in their study of the Bible. I have lots of books and I would consider most of them to be a waste of time. But I do believe that Schroeder has something to add to the conversation. Even if people are able to pick on what he says that is just a part of the process. That is what peer review process is all about. As they say you raise the flag and wait to see if they salute it or shoot it.
Joshua,
It doesn't matter
who's involved in using the statistics.
It's
how they're being used (or rather, misused) that was my point.
By using
only the Earth to generate the list of criteria for what other life-friendly planets
must be like, you end up confirming that only duplicates of the Earth
can be life-friendly. Which means that you end up confirming what you already know. You've filtered out all other possibilities by accepting only Earth-duplicates as viable locations for alien life. That's not investigating or discovering anything. That's confirming what we already know. Apart from confirming the anti-Copernican view that the Earth is special, favored and privileged, this exercise accomplishes nothing.
What should be done is to ask the question,
"What range of conditions will permit life to arise on other planets?"
If the answer is,
"We don't currently know, because we only have one example (the Earth) to guide us", then the next logical step is to
broaden the range of search criteria, not narrow them down. You start your search using a
b-r-o-a-d set of criteria and
then you narrow it down, eliminating as you go. You don't start with a very narrow set of criteria, because that runs the risk of eliminating potentially life-friendly planets that are somewhat similar to Earth, but not exact duplicates of it.
Do you see the logic of this, Joshua?
There's another basic problem with assuming that the Earth is somehow special.
That assumption runs counter to the Copernican Principle, which underpins modern cosmology, astrophysics and astronomy. If you begin with the anti-Copernican assumption that the Earth is special, then you can be sure that you are making a flawed and unworkable analysis, no matter how rigorous your data is.

I recommend that you carefully check Schroeder's work to see if he factors the CP into it, Joshua.
If he does, fine. If you don't know or can't tell if he does, then it'd be a mistake to assume that he does. You really need to find this out. You shouldn't just take it for granted that because he's highly respected, highly qualified and is based at MIT, he's therefore abiding by the rules of science. I say that because this scientist...
http://en.wikipedia.org/wiki/Francis_Collins
...doesn't abide by the rules and consistently disregards the CP.
Not using that principle allows him to promote the value of the Fine-Tuned universe argument as evidence for the existence of the Christian God - when the CP specifically disallows that kind of claim.
Please check Schroeder out with regard to his use or avoidance of the Copernican Principle.
Thanks,
E.I.
