I didnt say that, what i had said was these civilizations made pacts with these demons/"alien" for technology. This is going on still to this very day. Thats another discussion...
As far as dimethyltryptamine goes. When i was learning about being spirtual and was into Hinduism at the time. I learned how to synthesis dimethyltryptamine. And made lots and lots of it. Giving away to certain ppl, selling it, and smoking it (technically its vaping).
I kept trying to figure out y my soul didnt want me to keep using it. My subconcious kept telling me no. But i thought the shyt was amazing, the sacred geometrical patterns, colors so vivid, quite unexplainable really and everyone that had it agreed, its unlike any psychedelic they ever tried. To me its like lsd x10000 but completley different as its 100% spiritual.
