reason

Yeah pretty much. “Prove” is of course reduced to absurdity, too — it’s pretty easy to “prove” you don’t have a baseball, unless your standard of proof is that you can’t trust your own senses, experiences, or reason. Meaning: nothing is true, and/or everything is true. So complete intellectual anarchy/nihilism. Ummm, nice argument, theists. LOL

Can you PROVE that you exist? Can you PROVE that you have a mind? Can you PROVE I’m not a unicorn?…
