The US government hasn't acknowledge the existence of aliens, but in 2016 the CIA admitted to funding programs because they suspected the existence of aliens. It is very hard to find a good source to link though due to terrible SNR when you google "cia aliens"

The government also studied remote viewing, and the Air Force had its own UFO project called Operation Blue Book, and of course there was MKULTRA looking into mind control, but just because something is studied doesn't mean it exists, or gives practical results.

Sundevil (remote viewing) and Blue Book (UFOs) were '60s projects. AATIP and the UAP footage has been confirmed by the Pentagon itself, and even Raytheon's official site talks up the use of their ATFLIRs in recording the footage:

We don't know if the footage is aliens, but we do know that the footage is real.
