Yeah carving, how long do you think tool marks last on exposed granite? Guess I did have an answer for that one. I think most intelligent people do repeat what they've learned from others. Can you imagine figuring out chemistry and calculus all by yourself in one lifetime? To be fair I never said I was smart, as far as open minded, I would never say somthing is impossible but I do think of myself as a skeptic in general. I have visited one ancient site by the way as a guest on Native American land. I don't see how this is about
my knowledge. Like you said I repeat other people's ideas/theories.
I don't know why you are so emotionally attached to these beliefs. Far as I know, you didnt come up with them (just writing what other people have said/told you)

Obviously we have very different viewpoints on these types of things but I don't see why you take it personally. Debating/defending your ideas to other people polishes the nuances of your thinking and makes you question your ideas yourself. I think that's good if you have time/desire to engage in it. Just so you know I appreciate the obvious questioning nature of your mind, your pro-cannabis ideas and not to mention it is very impressive and respectable that you've attained the rank of brown belt. I hope continuing to discuss these types of things and disagreeing ends up making us friends more than enemies.
