"the anthropic principle is still valid when assessing whether the conditions under which life can exist can be duplicated elsewhere in the universe."
Well, the amount of variables drastically influences the amount of chance. We do not have all the variables available to calculate the chance. Chances are that it's a lot more complicated than we thought it was. Otherwise it would have already been done, most probably. We can't know whether it is one chance in a billion or one chance in a thousand, until we have created life (duplicated its origin if you like). And that is a fact. I have nothing against the principle though. Many modern appliances would not be available without it. But only with reliable data.
"neither of us a-priori know what happens if you take a planet like the early earth and leave it alone for a few billion years".
True, however, scientists are searching for the early stages of our planet. And I think they've come quite far in that field already.
"This too is ever so slightly slanted language in comparing life with dead material."
I think you understand what I mean though. Sorry for my use of simple language. maybe "non-living" would be more accurate. standard elements and molecules like they are available in other parts of the universe. iron, oxygen, water, etc...
"The wheel illustration is limited also . . . because we are armed with the knowledge that such an object is in fact designed."
Otherwise I would not have used it, right? The point I make with it is still valid. It is all about accepting or eliminating possiblities and finding keys to the real answer. In that respect, the illustration does a good job.
So what is the similar list of "demands" we make from theistic scientists?
Bohm, I think that is one of the best questions one can ask in this debate. I hope you can come up with a list of such conditions. I will think about these as well, but I might not be fully objective, and hence overlook some conditions.
Terry, did you notice I have not quoted a single bible verse? looking for traces of a designer in the origin of life and believing in the God of the bible are miles away from each other. That has no place in this debate, IMO.
