Couldn't it be that when people reject the premise of the evidence, the evidence becomes zero no matter what? The effect the evidence has on people or science as a whole is not necessarily the truth of the matter. It only matters when people need the whole of science to acknowledge it first.
I don't need science to tell me what the evidence says, at least until they really study it. Skeptics and proponents alike think there should be better science applied to the evidence, but you don't see science wanting to do it very often. I blame that on the first sentence in this post.
Truth will predict the future every time and the evidence will repeat itself when there is a legitimate creature responsible for it, so citing this as some kind of negative is actually anti-science.
It's funny that you ask for this in the best evidence thread, because that's what happens with real evidence, then you flip around and call it self defeating in this one.
