When people say they have proof earth is flat, 6,000 years old, etc. we say "prove it". When we keep showing them the proof, and they keep using circular logic, "Yes, I see that, but..." because they must accept it all on faith, and so much we. The debate is over.
I've had that debate--on HF. After pointing out the findings of geologists, paleontologists, archaeologists, etc., who produced gobs of evidence of humans and other life forms being around long before that, I asked: do you think they were all incompetent or lying? He said : "yes'. End of conversation.
