hey Stealth, this isn't a 5 hour show here or a Bible school
we give a few comments for short attention spans and move on.
sometimes i recommend a good seminary level book that they wont read or understand.
proof? it is everywhere, unless you don't wanna know. our Fake Atheists have zero desire for proof cept to be their own god.
ask them, they know or some kind of philosophical gibberish.
for more proof they could search out Biblical apologetics on the web...
here let me help you and the atheists:

i don't hold my breath, but it could happen like winning the lotto happens. they don't think their souls are worth a dollar; atheists don't think they have a soul, so the chance of them searching for truth is close to Zero.
