The Harvard astronomer dubbed Trump’s chief alien hunter starts by assuming UFOs human-made

Avi Loeb's White House panel has asked the Pentagon for videos and files on unexplained aerial sightings

A controversial Harvard University cosmologist who has suggested alien lifeforms could be sailing into the solar system disguised as meteors is leading the Trump administration's secretive new scientific advisory panel on security risks posed by UFOs.

Avi Loeb and his hand-picked committee have already begun looking into the origins of mysterious flying craft, now known as unidentified aerial phenomena (UAP), and last month asked the Pentagon for dozens of videos, images and documents of reported encounters and incidents, the Associated Press reports.
