Regarding if it is real or not, I like the way Neil DeGrass Tyson once addressed it.... (paraphrasing)
"You know, there is such a thing as the astronomy community. Both amateurs and professionals. These are people who pretty much constantly are looking up at the sky. Yet, UFO sightings are not more numerous among this astronomy community then in the rest of the population. In fact they are much much lower... Why is that? Well.... BECAUSE WE KNOW WHAT THE F WE ARE LOOKING AT!"
Indeed, if there really were UFO's (in the sense of alien spacecraft) in the sky to be spotted in the first place, you 'ld think that the astronomy community would spot MORE of them then the general population, considering the amount of time they spend looking up as opposed to the general population.
