You are missing one crucial point here plymco. Evolutionists and big bang theorists do not have faith in their theories. There are some that are fanatical, yes but they are not the norm or the scientists. You are coming from a reference point where answers are required, that IS NOT a scientific reference point. We theorize that the big bang happened because there is measurable evidence for it. That requires no faith whatsoever. We do not know where the big bang material came from. That also requires no faith because it is a simple answer of ‘I don’t know.’ You do not need to know the entire story to explore it’s outcome. Only in religion is the answer to all a requirement and that is part of why religion requires faith. Science requires evidence and theories are built on whatever evidence is available. They will change with more data no matter how well established the theory is.
As for evolution, it is taught as fact inn school because that is the best theory that we have at the moment and there is tons of evidence for the theory as a whole. There are questions and the theory itself changes rather frequently as more is discovered but that is at the very core of science. It is an ever changing exploration of the world around us.
I will never really understand why it is so difficult for the religious person to accept that science requires no faith and does not demand that all the answers are known. I cannot see what the problem is with simply acknowledging there are things that we are currently unable to explain.
Yes even the big bang requires faith that the observable expansion of the universe has been expanding since the big bang and will always continue to do so. We do not know whether there is some kind of force field or whatever out there that the furthermost objects in this part of the universe (assuming there could be even more 'universes' out there) will and/or do eventually reach and then reverse and go the opposite or a different direction.
The big bang is the most plausible theory that science has come up with for what science is a capable of observing at this time. But it is a theory, not a fact, and does require faith to believe it is the ONLY possible way things could be what we observe.
This is a laughably stretched definition of the word 'faith'. Equating the type of 'faith' scientists put into theories as say, the type of faith a Christian has, would be insulting the faith of the religious.
