Right, so your point about people not having hallucinations frequently is valid. But most people do see optical illusions.

So it seems strange that you have jumped to the conclusion that these must be real UFOs since most people do not hallucinate.

I did not jump to that conclusion, you are putting words in my mouth.

The whistleblower reports of the existence of a research program that he was briefed about. He testifies this program was stuying non-human technology, among that functioning craft, aka "flying saucers".

The determination of it being non-human in orgin was due to extensive material analysis, evident morphology and working characteistics of those devices.

"Someone claims that someone else told him material exists that is from aliens."

> "Someone claims that someone else told him material exists that is from aliens."

I think I take your point: he doesn't have firsthand experience seeing the evidence.

That said, the quote "Someone claims that someone else told him material exists that is from aliens." doesn't by itself convey the significance of these other people being high ranking intelligence officials. A trained intelligence professional has much more analytical skill and credibility than a person randomly sampled from the U.S. population.

> The Debrief reported that Grusch’s knowledge of non-human materials and vehicles was based on “extensive interviews with high-level intelligence officials”. He said he had reported the existence of a UFO material “recovery program” to Congress.

> “Grusch said that the craft recovery operations are ongoing at various levels of activity and that he knows the specific individuals, current and former, who are involved,” the Debrief reported.

> In the Debrief article, Grusch does not say he has personally seen alien vehicles, nor does he say where they may be being stored. He asked the Debrief to withhold details of retaliation by government officials due to an ongoing investigation.
