I have noted a few atheists make the claim that God does not exist because there is a 100% lack of evidence. Its a very famous atheistic apologetic shared by many.
There's all kinds of evidence, obviously... it's just that none of it is good enough. Or, should I say, none of it is as good as even the most trivial piece of evidence for something that can be demonstrated to anyone/everyone with relative ease. Like "air", for example. Theists used to use that one because it is/was something you can't see. But one might, for example, blow up a balloon, and then deflate it, to demonstrate that
something was in that balloon, filling it up. And just
that alone is thousands of times over better evidence for the concept of air than anything that has been presented as evidence for a god.
There's your actual hurdle - so don't just argue against the low hanging fruit of "some atheists say zero evidence." That doesn't matter. What matters in this discourse is that you provide some compelling evidence. If all I had to defend the notion "air exists" was word salad and a bunch of attempts at brandishing convoluted "logic", you would likely remain unconvinced, or be suspicious of my motives... and for good reason!
So I would like to ask the atheists who use this argument about theism and God. What is the test you have developed to do this elimination?
I don't need evidence against to simply disbelieve because of lack of evidence for. It's the exact same reason I don't believe in unicorns, fairies, leprechauns, or big foot. Once those things are presented with a demonstration of how their existence is determinable within our shared reality, then there will be warrant to believe. Not until then however.
