Why are ufos real?

"UFO"s are real, and have been observed from many locations over many years.

"UFO" is the acronym for "Unidentified Flying Object". Thousands of people have seen things

in the sky that they couldn't identify. Therefore, since the observer in each case had no idea

what they were seeing, each one was, by definition, an unidentified flying object, or UFO.

And that's as far as you can go with it. If the question is asking about UFOs as spaceships,

things from outer space, carrying space aliens, abducting humans, there has never been a

shred of credible evidence of any of those things that stood up to serious examination.
