Defines “knows”. Are you saying that you have read or seen actual intelligence that prove the existence of extraterrestrials? Or, are you just passing on an accepted “gestalt” of your peer group without any specific evidence?
If the later, I don’t see how that is different than anyone who attends church discussing the existence of God. Not that I am putting down faith or belief in the Divine.
As for extraterrestrial, I do not disbelieve, and in fact hope they exist, but it would take a lot more than a “wink, wink, nudge, nudge” knowing smile to convince me of that.
I’ve seen some and have had conversations with VERY high-level men who spoke as if it were an accepted fact. And yes, it is considered CW within that set, all the way down to lowly Spec/5’s who use 100-mile-an-hour tape and overlays in their daily rituals. Can I prove any of this? No, I have no access anymore, nor do I want any. I know it sounds like “Ulsterman’s Insider” and that kind of thing (although that might be real, too.) but I know what I know. It was quite an eye-opener for a 19 year old, as you might imagine, and I really haven’t gone into it too much, as I take my oaths seriously. But it’s 2010 and the Cold War is long since over.
The physics of our situation (roughly 300 billion galaxies in the universe, each with roughly 100 billion stars, each with an unknown number of planets) make it literally impossible that we are alone (at least as impossible as you winning the powerball every day for the next hundred years). The big question is whether ET intelligence has visited us.
