Dr. Steven M. Greer

http://en.wikipedia.org/wiki/Steven_M._Greer, http://www.disclosureproject.org, http://www.cseti.org
An educated man that's interested in exploring the concept & the possibility of intelligent life throughout the universe. Of course, for many the claims are just too out there.

Is Dr. Greer so driven by the possibility that he has already arrived at a conclusion?

Many say, don't bother being that curious about the universe & existence, in general. Fortunately, there are many curious people around & they don't necessarily have to agree on every point on whats known & whats unknown.

Of course, there is a skeptical perspective towards what Steven Greer has been doing over the years.

Perhaps Steven Greer is providing an interesting blend of speculation & entertainment. I still like to hear what he says & many people will arrive at their own conclusions about various claims & cosmic mysteries.
