It's been by turns frustrating and fascinating and wonderful beyond imagination. If what I suspect is true, it's one of the most important milestones in human history to acknowledge that we are not alone in the universe.

There are more than 100 first- and second- hand witnesses to the retrieval of an extraterrestrial spacecraft and at least four extraterrestrial bodies from a crash which occurred in July, 1947, 75 miles northwest of Roswell, New Mexico; written and videotaped testimony from several first-hand witnesses who are respected military officers have been obtained.

It is an understatement to say that the time has arrived for a serious and open international dialogue regarding the possibility of future interplanetary relations. In no other area of human experience has so much evidence existed for so long, and yet been attended by such a paucity of serious research and analysis - at least in the civilian domain. While the subject matter of UFOs itself is extraordinary, it is the absence of a serious human response to it that is most extraordinary.

Back in the early 1960s, when I was eight or nine. Some neighborhood boys and I saw a disc-shaped, windowless object that hovered, silent, then simply vanished. My parents said, "That's very nice" and ignored it, but I knew what I'd seen, and it was life-changing.

It was one to three football fields in length. It was massive, about 300 feet above the ground. It had three lights on the points of its triangle and a large red light beneath.

Alas, our technology has marched ahead of our spiritual and social evolution, making us, frankly, a dangerous people.

The evidence that at least one extraterrestrial civilization has visited Earth is extensive both in scope and detail. In its totality it comprises a body of evidence which at the very least supports the general assessment that extraterrestrial life has been detected, and that a vigorous program of research and serious diplomatic initiatives is warranted.
