How do you know what can be used as evidence without using logic at some point prior to obtaining whatever it is that you call evidence?

Well I certainly don't go look for some useless philosopher with his head in the clouds for an opinion on what is and what is not evidence. I'd probably get a lecture on postmodernism or metaphysics or some other foolishness.

That is your problem and the reason you end up with just-so stories. Your "useless" philosopher was the person who gave you "falsifiability".
