Do you think aliens in ufos have visited Earth? (And all things UFO)

I wish Avi would back off on his claims a little bit.

What he found was most likely part of a meteor that originated from outside the solar system. He shouldn't be suggesting it's aliens.

If he discovers evidence that it is aliens, then say it then. He's just setting himself up to look bad.
Maybe there is evidence that it is manufactured or worked in some way, not natural? I agree with you though, don't make those claims unless you have something to back them up with.
But, that would make it “identified”
That's the point. If the whistleblowers are claiming they are real, then they are identified as non-human manufactured. Therefore identified as extraterrestrial, no longer a UFO/UAP.
