As a study of the past, material science can only investigate 'what appears to have been, based on current evidence', and not 'what actually was' in the very possible case that these two notions: 'what appears to have been', and 'what was', do not converge. It is not sensible for one conducting a scientific investigation into 'what was' based on current evidence to assume otherwise, for then they have no foundations. But just because this is a necessary assumption for the investigating scientists neither makes it true, nor implies that others should take on this assumption. The alternative is that the past cannot be deduced logically from available evidence, and then one must look to other sources of inspiration. Scientists do not do this, but many religious believers do. Thus we find that the two camps may be standing on different, incompatible, foundations, both of which can make sense depending on your standpoint. Total victory on the part of the evolution brigade is as absurd as an 'it's all in Gen 1' approach, being possible only with the kind of conquest over peoples thinking and beliefs that the Christians and Muslims have tried in the past. (Guess what: other belief systems survived, and a new one is now in the ascendency, but needs to learn from past attempts at conquest of belief and realise that there are better ways forward.) On both sides, though more on the fundamentalist religious side, people need to be encouraged, gently, to open their minds to other possibilities besides the ones they take on faith. And this taking things on blind faith is, so far as I'm concerned, philosophically unavoidable. Anyone whether of a holy book or a science book, who believes otherwise is deluded.
