Professor Avi Loeb said there are clear signs that the comet known as "3I/ATLAS" could be an alien craft. "We should put all possibilities on the table that it's a rock, a comet, or something else until we get the evidence, the data that will tell us what it is," Loeb said in an interview with WBZ-TV's Courtney Cole.

A new interstellar object in the solar system should be investigated for the possibility that it's an alien craft, according to theoretical physicist Avi Loeb.
