Well its a very interesting subject. I have read tons of books on the subject and after all that I am none the wiser
Though I do have some kinda opinion now.
I believe we are visited, whether the phenomena are from distant stars, the hollow earth or wherever I don't know.
For sure some highly competent observers have reported things, so I feel that its a safe bet to say that YES there is something happening, this point seems to be beyond dispute.
Who or what they are is still totally open to question. Who's to say they are not animals, robotic probes, lil green men.
Reading a wide range of reports you begin to see that it may be that we are being visited by many different things, not necessarily all from the same place.
I am pretty interested in astronomy, there's been so much time in the past that our whole solar systems rise and decay has been played out millions of times all around the universe already.
It would seem to me quite arrogant to think that we are the only ones, if not a little scary also, to be out here alone scares me more than thinking of a universe teeming with life.
It seems a remarkable coincidence for everything to have happened the way it has to produce us, maybe so remarkable that it has not happened anywhere else.
If it turns out we are alone then we really need to get a grip on our poisoning of the planet. Its a fragile place and it might be the ONLY oasis for us in the whole universe so we would be wise to get a grip on it now and stop destroying our nursery.
I could speak for hours about all this but have work to do so there you go.
