I am certain that Soma was an Ayahuasca analog and that the moses sacrament was smoked DMT , plus later after recieving the 10 comandments an Ayahuasca analog.
I think so too. The discovery of ayahuasca is often described as a miracle that took place in the Amazon, but there is no evidence to suggest that Ayahuasca analogues were not discovered in other places of the world, but lost in due course of time.
I've never heard anyone say this, but my guess is that human beings living in the prehistoric world must have sampled many of the leaves, seeds, flowers, roots and bark in their environment. Undoubtedly they must have stumbled upon a good source of MAO-inhibitors, and noticed its calming effects. In some cultures such plants may have been used, at least by some, on a daily or weekly basis. Just imagine a small tribe living somewhere, eating or drinking this MAO-inhibitor regularly.
Such a group of people will try out other plant parts from the environment, trying them raw, trying them cooked, etc.
In such a situation, some members are bound to get dosed by a DMT-containing plant one day (by chance/ grace/ destiny/ synchronicity/ telios/ the hand of God). It wouldn't take much time for these people to figure out that the "new plant" only works for those who first take the "old plant".
It's just a theory, but think about it: why is the Banisteriopsis caapi vine more sacred than the Psychotria viridis. even though the latter factually opens the doors of perception?
Banisteriopsis caapi has many medicinal qualities aside from the MAO inhibition. It might have been in use for hundreds or thousands of years before the psychoactive qualities of Psychotria viridis were discovered.
To come back to GOD's argument, we indeed have an MAO-inhibitor with a long history of usage throughout Asia and the Middle-East (or wherever else it may have been): Syrian Rue. It just needed to be a popular drug (to combat stress, insomnia or depression) for a short while before someone got really high from eating too many leaves from any of the DMT-containing trees and grasses (or even mushrooms) growing all over the place back then.
I'd love to believe that spirits, gods or even humanoid aliens revealed to select shamans the secret of ayahuasca, but the above scenario seems just as likely. And as I mentioned between brackets, it doesn't deny that such a discovery was guided by divine providence.
A similar argument can be made about the discovery of astrology, especially within a culture of people using psychedelics. For the most complex, advanced and reliable methods of astrology were not discovered in recent years, but many thousands of years ago, by the same Soma-drinking people mentioned by GOD. It may be tempting to believe that Lord Brahma revealed astrology as a complete software package to Parasara Muni, as pious Hindus tend to believe, but a more rational course of events is just as likely, without denying the hand of providence ("Brahma"), and certainly not the aid of psychedelics ("Brahma")!
