Middleman -
I won't take your not substantiating your claim as proof that it is false. But please don't be so hasty as to deny things which you know are at least a consensus position without at least a modicum of backup.
Your criticism of my first point seems to miss my intent. It was not a scientific claim. Science does not really have arguments, it has experiements (usually). It is a claim about logic and arguments which derives from a general modern theistic philosophy on the characteristics of God, and it holds. It is also false that science is "silent" on the matter of god. There are certainly mainly claimed lines of religious evidence which have been investigated and falsified by science. Thus the god-of-the-gaps situation. Some prime examples are:
1. Prayer.
2. Miraculous healing.
3. Channeling the dead.
4. Demon posession.
5. Religious relics.
6. Statistical claims that being a member of religion X makes you a better person or promotes successful marriages compared to non-believers.
7. Claims that corporal punishment of children causes them to be better adjusted adults than do their non-physically punished peers.
8. The claim that complexity can only be the result of teleology - or even that it is more probably so.
9. The claim that emotions and personality are completely metaphysical properties of an immortal soul.
10. The claim that humans have existed on earth for a short period of time. (Your objections not-withstanding)
11. The claim that "religious" experiences are supernatural (At least some have full natural explanations)
Your claim that science is "silent" on the matter is clearly false. At the least science has shown that a vast array of religious beliefs are poorly supported by the evidence and have simple natural explanations. Whether a modern reinvented god for which there is no evidence exists is not a scientific question. It is a philosophical one. I didn't even mention evolution because it will further detract. Though I would add to the list above "The claim that humans are not animals" and also "The claim that animals were created in fixed kinds."
Your second criticism, as I understand it, seems to again miss a distinction between a scientific argument and a logical one. In other words, one based on natural evidence and one based on words and symbols.
It is technically possible that a god exists depending on one's definitions. This does not mean it is rational to conclude that such a being exists. It is equally possible for almost any of the available gods to exist. These are vastly different points. My concessions to theists, and the current state in the philosophy circles, is close to as follows:
While there is no argument that should rationally convince one to accept theism from a neutral state, there are successful arguments which justify a theist maintaining her belief in a god for other reasons.
The scientific arguments would be very different than the philosophical ones. And since the OP was about philosophy primarily, my comments about the arguments are largely philosophical. I raised the dating issue in response to your denial of dating methods.
