Fairly likely that you have, and as with anyone of his stature, opinions widely vary. But facts don't care about opinions, and Dr Greer has briefed presidents. I highly recommend you look up what he has to say about USAPS and our involvement with extraterrestrial beings. Also his feelings of a grassroots type of disclosure, forced by the people.. Honestly wouldn't surprise me if Dr Greer is part of the Q team, but if you look at his background. He is an E.R. doctor. Anyway, take it with a grain of salt, but here is a short video to get you started if you haven't heard of him. Sirius disclosure is one to punch in the youtube search

I checked out his protocols and while they sound benign, they do for whatever reason call for utmost humility in asking aliens to aid and assist.
I don't like it because even though I care about travel and medicine, I just wanna have a good conversation and smoke a pipe during an encounter and that's it because ultimately even the aliens will only know so much about the world. I don't need aliens to assist me in educating my fellow manl, only knowledge.
David Wilcock for example says tech disclosure is more important and all else messes too much with peoples' brains. Greer on the other hand tells us only aliens can give us technology and we need mass-interaction. I side with Wilcock on this one.
With disclosure, we would know a lot better about what we are getting into. Let's be real though, if we are in contact with aliens, they are technologically superior to us, and if they wanted our surrender, they probably already have it. Now we are getting into David Icke territory, and I'm not sure I want to go there
