dunwerkin - glad to see that people are getting some benefit out of the discussion... enjoy your course.
Theland - Any scientist worth their salt will not ( or should not) have faith in anything, since faith is belief in the absence of evidence, and that is ( or should be) anathema to any credible scientist. What they very well do have, and this is seen time and time again, is often a passionate belief in a particular hypothesis ( a model of how something might work, with observable evidence to point to it). That is why you will often see fierce debates between rival camps of scientists, who have differing hypotheses about a phenomenon. It is precisely these debates that give science its edge, since comparison of the evidence in support of rival hypotheses, based upon experimental observed data will eventually lead to one or more hypotheses being discarded in favour of the one that best fits the available evidence. This is how scientific theories arise ( and remember there is a deal of difference between a scientific theory , which is more like a Law, and a laymans understanding of the word) where a common consensus is adopted.
Science therefore is both progressive and self correcting....hardly something that religion can claim.
God as creator, as active player in our individual destinies has been receding for some while now as science and rationality shine a light into the mysteries of origin, and there are very few places where sufficient mystery remains... the biggest of which is probably the big bang. and what was there before, if indeed there was a before.
