can evidence exist for something that doesn't exist?
what if you saw foot prints in the woods, and claimed that was evidence of big foot? and, we'll assume big foot doesn't exist. is it fair to call that evidence to begin with, then, if big foot doesn't exist?
or we have more speculative things. we have lots of credible people like pilots who say they see flying objects doing things in the skies that aren't possible to our understanding of physics. is that evidence of UFOs? would it be evidence if UFOs didn't in fact exist?
an atheist at this forum made a good point once... he said, we shouldn't be so quick to call things 'evidence' if all it is is 'consistent' with a certain theory.
i know, to get more religious, a lot of philosophic arguments for God exist, but they could just as easily be called 'merely consistent' with the the God theory than 'evidence for' the God theory. when it comes to these philospohic arguments, for everyone you can make, there is a at least plausible alternative non God argument that could be made.
then there's more scientific arguments, less philosohical. i do think when we get into things that look like supernatural healings, and atheists becoming theists during NDEs, that those are more in the realm of evidence and less about merely consistent with the God theory. but, it would be possible to spin even those things, if you have a darkened heart and mind, into things that are merely 'consistent' with the God theory and not look at them as evidence.
