here is my reply:
Ben, et al.,
Hello.
Of course Steven Greer is a wholly-purchased "asset" of Lawrence Rockefeller and the Rockefeller family. The Rockefellers are uber-Cabal.
Lawrence Rockefeller financed UFO research which was tame and controlled, (nothing too serious saw the light of public view). Meanwhile Steven Greer's "credibility" as an "industrious UFO investigator and advocate" grew. Greer is a "sleeper" agent.

in the light,

i will try contacting Dr Greer himself, see what he says.
