Hello all?. My, you have all been busy while I have been at work! :-)
Trusting in a physicalist / materialist / empiricist philosophical framework is as much an act of trust as trusting in a God, because neither can be proven definitively. - I Think I might scream if I hear this again!
Holo, I can completely comprehend that you have a "belief" and that you have trust in this belief (it is a wholly alien concept to me, but I can accept that some people need this in their life - I don't mean that in a patronising way and I genuinely don't look down on anyone who does (much - joking?)). Please try to put your "belief" to one side for a moment and consider the following (you don't have to accept it, but just consider it and give an honest appraisal of it with your "belief" hat off for a minute):
You will find very little atheists in the world (including Dawkins and EVEN me), that when asked "is there a god and can you prove it" will ever say "There is no god - fact". If you ask an atheist that can explain things well (some can't) you will find is they will respond that "the likelihood of there being a good is probabilistically very low indeed, and so low that we can be very confident that no god exists. This is a scientific theory that is fully supported by all current scientific data and there is no evidence to the contrary. However, we can not say definitively that no god exists because the evidence does not support this". (this is where atheists usually move onto Russell's teapot, or my unicorn banter - but only because people of religion always say "well if you can't prove that god doesn't exist then he must" - which just angers us as a concept because it just goes to show that no one was listening to the very carefully and scientifically correct worded probabilistic argument!)
This probabilistic statement is in no way a "belief" system in itself, because the scientific method is being used (no guess work, no ignoring data and no skewed logic). If someone were to say to you "There is no god and I can prove it" then they are wrong (based upon current available evidence) and I would agree with you that they have their own "belief" system (however more credible than religion this 100% atheist "belief" may be).
Does this help?
One of the big problems in my view is the media and I personally think that poor reporting of science is a real issue. The global warming "debate" and the MMR vaccine "debate" make it look to the layman that scientists can't agree between themselves, thus it must be a belief system. But the truth is that these "debates" are caused by a small minority of rogue scientists and are not supported by the vast majority of scientists (the credible scientists). Sadly the media think that they have to create "balance" to everything and think that they have a duty to give airtime to the "counter argument" without the technical knowledge to make the judgement that "counter argument" is utter arse! This is very damaging for credible science and does not help with the religious "debate"
I can't remember who was asking about the DNA of Jesus, but there is some good information here:
