In personal counseling, I am not the only one who has helped people with demonic spirts and/or activity in their lives who encountered beings who claimed to be 'aliens' or 'multi-dimensional beings' that turned out to be devils in the final analysis. Understand this brethren: devils are liars and decievers like their master Satan. They intend to decieve the whole world and usher in antichrist. What more clever way to do it than to come as 'peaceful' aliens from another world (a la Close Encounters of the 3rd Kind & 'V')? I personally believe that the so-called 'E.T.'s' are devils in disguise and many New Age, and UFO proponents are buying into their message ('we bring you peace, new technology, & One world order!' yeah, sure.
I have been watching this issue for 45 yrs and I've observed that it's getting harder and harder for the skeptics to deny what is happening in our skies. But as we progress towards the coming of our Lord we are seeing even high level government leaders and military people come forward with startling information about a presence of unknown beings in our world.
This isn't meant to be an exhaustive post but let me show you the only two times I've ever taken pictures of what might well be UFO's in them, neither time was I even looking for UFO's much less expecting to find them.
Below is a picture I made about six weeks ago. A low flying crop duster buzzed our church building so I ran out the back door of the parsonage (next door) & snapped two quick shots as it flew over:

The pictures are too small for this format but notice to the upper left of the crop duster the two small lighted orbs. Here is the other shot take about 3 seconds later:

So I measured the distance (in millimeters) between the corner of our church roof and the crop duster as compared to the lighted orbs and it became clear that they were following the small plane. Then I did a close-up:

One blue orb and one white orb. Mysterious indeed!
Several weeks later I saw a spectacular full moon from our front yard and got a few pictures of it:

But after I took the second picture I got this:

The two red orbs were unseen by me when I took the picture. Reminds me of the red orbs seen above Jerusalem after the bright light was seen above the temple mount. But what has been seen in London, England, El Paso, Texas, New York City, Mexico City, and all over California the last few years is just astonishing with in some cases, dozens or even hundreds of people viewing strange phenomena at the same time. The below video footage of a tornado southwest of Oklahoma City was captured by KOCO TV. It literally rips apart a semi while being surrounded by UFO's. Notice that one of the lighted orbs disappears behind the tornado and then re-emerges on the other side. The news people didn't mention the orbs but they can't be missed:
Here's a better view of the same thing:
