In regards to proof, someone else a few days ago was requesting "concrete proof" yet in my mind I feel like the whole proof issue is misunderstood as its only US and our incredibly rigid programming that makes us seek this narrow view of 'proof' - we are taught from infancy that we ARE our bodies and therefore we define LIFE ITSELF by only its PHYSICAL nature and if something doesn't exist in the physical world, then we say it doesn't exist at ALL as a result. But the irony seems to be that REAL contact with ETs occurs often, but because it occurs on the non-physical etheric and astral planes, we judge those experiences/planes to be "not as good/not as real" due to our massive investment in the physical world being ALL of reality.
Its quite possible we actually exist in 7 planes simultaneously with the physical plane being the lowest. We easily may one day discover that ETs are more in tune with the higher planes and therefore their contacts with us mostly occur on these other planes and that they must look at us as being so "silly" because WE are the ones who invalidate the experiences due to nothing but our own judgments. I previously mentioned a site I really enjoy called Galactis.net (
http://www.galactis.net/en/documentare/) and these Romanian guys have Etheric Plane contacts all the time with a Sirian mothership - they are very clear to insist they are NOT channeling information and that their experiences are DIRECT communications via the subtle etheric plane. So they are most definitely having real 'proof' yet it is not occurring on the physical plane so most people would consider that to be 'lesser proof' when it in fact may be MORE.
In regards to the physical plane, the proof is everywhere these days - there's over 1 million UFO sightings reported in the last 10 years worldwide - these include some VERY credible people. Imagine your home for a second - if there were literally ONE MILLION people lined up outside your front door telling you the pizzeria down the street was on fire and ONE PERSON (the gov't) at your back door telling you it wasnt on fire, WHO WOULD YOU BELIEVE?
The real issue is that people's judgment systems all seem to require this 3rd-party 'governmental acknowledgment' before they will accept it as 'proof' and that is the big joke as at some point, we the people will all believe our own experiences and each other to where we'll NO LONGER NEED OUR GOVERNMENT'S ACKNOWLEDGMENT TO ACCEPT IT AS TRUTH. Besides, the gov't would never acknowledge it anyway unless they were forced to as they would have to admit that not only have they been keeping it a secret, but more importantly, the reason theyve kept it a secret is because THEY MADE THE WRONG CHOICE - they chose to align themselves out of greed with the negative factions when they had a CHOICE to instead align themselves with the positive ones. As such, they spend trillions of dollars to make the keeping of this secret their #1 agenda - and they do a pretty amazing good job considering the truth lies in plain sight (the stars you see in the sky every single night). Part of the way they do this is by controlling the media and promoting disinformation, part by intercepting communications to be able to 'delete' proof of saucer crashes etc, part by programming the masses via extremely biased education and part by programming the masses to focus on the concept of the physical world being the ENTIRE world.
At this point I think that over half the UFO's people see are from Gov'ts and SSPs anyway so even if one "landed" to prove itself, it could easily be dismissed as a man-made Earth-originating craft. So even that would not satisfy the skeptics. My thought is pretty simple - yes, physical proof would be great, and necessary to the masses at the moment, but its somehow become less and less necessary for me personally at some point in my spiritual development as its only our intense societal programming that makes us desire and demand proof in the 'physical plane' to be the #1 type of proof when in fact, it may just turn out that physical-plane proof is essentially the lowest form of 'proof' in the universe.
