Testimony is not evidence, and using the passive voice ("given explicit authorization", by whom? why does this matter?) is an explicit argument from authority. Physical evidence or nothing. There are no shortage of credulous people in the world happy to bask in the glow of attention.
Consider the counter-factual. If indeed there are aliens here, and have been here for decades, why not centuries? Why haven't previous generations found them, and not known their true origin? How curious that these artifacts only started appearing in the space age, when if they had appeared previously they would have been attributed to a religious origin (and not only not suppressed, but shared widely as evidence for God.)
Note: if aliens are here then FTL travel is not only possible but common, and easy, and this would undermine a great deal of verified physics. To get around this you'd need a conspiracy across all physics research (a la the SF novel "The Three Body Problem"). I'd also add that if going to other planets was like sailing a ship, then we could expect (lazy, sloppy) tourists to come around who don't "toe the line" when it comes to staying hidden.
Extraordinary claims require extraordinary evidence, and without it all such claims can be safely ignored (and indeed, can and should negatively impact the people making them).
Grusch was given access specifically by an act of the U.S Congress to investigate UAPs. Watch the CSPAN link of the congressional hearing I provided for the full details.
Read the link to "The Crowded Galaxy" theory for what's probably going on based on that testimony. It answers all your questions. There are probably millions of planets with life in the galaxy. We're not remarkable except with how hyper-violent and invasive our species is, which is why they're keeping an eye on us. We evolved here so we have the right to live here, but we don't have any rights to live anywhere else in the galaxy. Transforming is probably a ghastly notion to them.
The government also studied remote viewing, psychic powers, and tried to control people's minds with LSD. The government has been investigating UFOs since Project Grudge back in the 1940s. None of that is evidence that remote viewing, psychic powers, mind control or UFOs are actually really alien spacecraft.
David Grusch repeating second and thirdhand claims about alien conspiracies is not evidence that those claims are real, nor is investigating UAPs evidence of the existence of alien spacecraft. None of this is actually evidence if anything, it's literally the same non-evidence the UFO community has always believed in as a matter of faith, and insisted that everyone else take as proven, self-evident fact.
Worth remaining a little skeptical. Could be Project Blue Beam, the plan for a fake alien invasion, that's been talked about for literally decades in conspiracy circles.
