Indeed, they usually say science can't prove anything. And then, of course, they ask for proof of whatever it is that you said. Some, like Coyoteman, go so far as to say that the word "truth" must be excised from the vocabulary of science.
That, as I have pointed out to you many times, comes from a CalTech physics website. But for those with a short memory, here it is again:
Truth: This is a word best avoided entirely in physics [and science] except when placed in quotes, or with careful qualification. Its colloquial use has so many shades of meaning from ‘it seems to be correct’ to the absolute truths claimed by religion, that it’s use causes nothing but misunderstanding. Someone once said "Science seeks proximate (approximate) truths." Others speak of provisional or tentative truths. Certainly science claims no final or absolute truths. SourceIf you want TRVTH, though, just ask the creationists here. They'll be happy to fill you full of it. But the problem is, each will give you a different version of the TRVTH and defend it to your death. That's why the Religion Forum has such tight moderation rules.
Thanks, science does just fine by seeking to be accurate. That's plenty good enough, don't you think?
