So many people on this site cling to that as the only possible explanation and disregard any other theory as being flat out wrong.
No single theory can be applied to all cases. Some are misidentified normal objects or phenomenon, others seem to be unexplained as anything else. The
best we can do is take the evidence at hand, analyze it, and draw our conclusions based on this information.
It is my belief that ufology took a major downturn when it became a foregone conclusion that UFOs were ET in origin.
I don't think ANY UFOlogist believes all UFOs are ET in origin, but in some cases, that is the only theory that seems to fit the evidence.
Here's an example. Recently, I've been entertaining an idea about Roswell. Here's the hypothesis I was going to research:
What if it really was Mogul that crashed, but they thought it was a Russian Balloon at first, and were later too embarrassed to let anyone know?
This would explain the steps they took (flying it to foreign tech bases, etc.), and the cover story and coverup. Their embarrassment could even
explain the duration of the coverup.
But, then many holes appeared...
Why did so many military officers come forward testifying to the strangeness of the debris materials, etc.? Most never saw a penny from such
Why did the Air Force feel the need to coverup the reports of bodies in their report?
Mogul Flight 4's recovery date only fits if you accept Brazel's testimony after being in military custody, as to when he found the debris.
Nobody's ever produced the "flowery tape" that Moore claims is responsible for the accounts of I-Beams with hieroglyphics on them.
Why couldn't witnesses identify simple balsa wood, foil paper, and balloon debris?
I'm a firm believer in trying to find a more plausible explanation before jumping the gun to an ET craft being responsible for a UFO sighting, etc.
But, in some cases, it's the only explanation that fits the evidence. Now, with additional evidence, some cases may be able to be more satisfactorily
explained, but it's good to be open to at least the possibility.
But, thinking every light in the sky that you can't immediately explain is a UFO, that's just blind belief.
