This may be considered way off topic, but is of such great significance that I felt compelled to share this interview and intermingled video footage from the Space Shuttle and Apollo missions, that will at the very least have you ponder the possibilities.
Dr. Edgar Mitchell earned his doctorates from several Universities and was one of the astronauts to have walked on the moon. He claims that the UFO presence is here and has been visiting this planet for perhaps thousands of years and that contact has been made. He believes that there has been a government cover up since the early 50’s and that this information has been withheld from the public at large. He is also the founder of IONS Institute of Noetic Sciences which is
located in Northern California that conducts and sponsors leading-edge research into the potentials and powers of consciousness—including perceptions, beliefs, attention, intention, and intuition. The Institute maintains a commitment to scientific rigour while exploring phenomena that have been largely overlooked by mainstream science.
This may sound like X-Files stuff, but when you hear it from a man of such high esteem, it makes one sit up and take note.
None the less here are a couple of videos that you may find illuminating and hopefully thought provoking. I most certainly was taken aback by his revelations.
