And sorry for the OT argument, but so far I believe there is no evidence of UFOs, just people saying they have seen them or even recounting to have been abducted by aliens. But there are people who are convinced they are Napoleon or Jesus Christ, so we cannot really believe them in their word.
Personally, I am agnostic about the existence of aliens, that is, if there are other intelligent beings in this galaxy, for example, they are either too far away and unreachable, or they keep concealed, so to all practical matter it is as if they don't exist at all.
I also listened to some very logical arguments as to why it is unlikely that in this galaxy there are other evolved beings, and the logic was valid. That does not mean that it is true, but the logic was there.
We may be the only evolved or semi-evolved beings in the Milky Way. And the other galaxies are too far away to establish a contact unless hyper-evolved beings know how to create wormholes and drop by planet earth. But then, why do they keep so well concealed?
First of all I think there is clearly a difference between being convinced that someone is a Jesus Christ or a Napoleon and seeing UFO’s. I myself know that I have seen UFO’s but I am not of the opinion I know who or what they were. But I do believe that coming up with some of the explanations I’ve heard for what I saw are feeble. Lastly, I would say, with no offense to mccoy’s assertions, his views appear rather contradictory in light of the fact he has so much positive to say about Paramahansa Yogananda. Yet he is still skeptical about Yogananda’s ideas about the Yugas. Knowing mccoy as long as I have and hearing his views as long as I have I would say quite assuredly he is a born skeptic and unless the evidence can be replicated and verified he usually does not accept the views. I believe it is important to remember what Paramahansa Yogananda said about the skeptics in Science; ‘Let them go into the inner laboratories of their own meditation to prove many of these personal assertions that individuals make to see if they are true’. Babaji told Lahiri Mahasaya ‘not to waste his time with sensational seekers who are not willing to spend time building up their own faith enough to see and experience ‘miracles’ from the spiritual realms.’
There are many concepts and ideas that can only be proven by our own spiritual search. Science has its own limitations in the sense that many spiritual truths may never be proven in a science lab. They can only be proven in our own personal soul searching.
I'm having a hard time keeping up- am not very scientifically oriented... But I wanted to interject something- I think there are signs of such civilizations and it would mean attempting to understand reality outside the faculties of the human experience. For example, just because we experience linearity and distinct forms through space-time- does not mean reality is not cyclical or layered, superimposed. Think of the flower of life Once we identify ourselves with the energy we perceive as separate from- things like interdimensional travel start to make sense. All of this, 3D and space-time is very real, but it does not mean reality is confined by the limit of human experience. If people are witnessing UFO's, what are they? Where do they come from? And how can an ET who identifies itself from Pleiades appear and communicate with Beings on Earth??
