Aliens may not be hiding somewhere in a distant galaxy. They could already be here, according to Harvard professor Avi Loeb, who says humanity may simply lack the scientific knowledge to recognise what it is seeing.

Speaking on Jesse Weber Live, Loeb pointed to unexplained aerial phenomena reported by US agencies and revealed details of a recent meeting with government officials, arguing there is still no clear evidence some of these objects are made by humans.

Loeb Says the Aliens May Already Be Here

Asked which explanation for the famous Fermi paradox he finds most convincing, Loeb gave a strikingly direct answer.

'The answer to Enrico Fermi's question is, where is everybody? They are here. It's just that we haven't realised that,' he said.

The Fermi paradox refers to the apparent contradiction between the enormous number of potentially habitable worlds in the universe and the lack of confirmed evidence for intelligent extraterrestrial life.

Loeb argued humanity should be more cautious about assuming it understands everything it encounters. Modern science, he noted, has existed for only a relatively short period compared with the age of the universe, while many stars are billions of years older than the Sun.

For Loeb, an advanced civilisation could possess technology so far beyond human understanding that scientists might not immediately identify it as technology at all.

He illustrated the point by comparing an advanced device to a mobile phone discovered by a cave dweller, saying the person might simply see it as an unfamiliar type of rock.

US Officials Are Seeing Things They Cannot Explain

Loeb's argument gained an unusual connection to government investigations when he discussed his recent involvement with US officials.

He said the first meeting of the UAP Science Advisory Council, which he leads, took place on 31 August at the office of the Director of National Intelligence.

'The government has things they don't understand,' Loeb said.

He added that officials are interested in determining what these objects are and claimed it is 'not obvious at all' from the information currently available that the phenomena are human-made technologies.

The comments do not amount to a government confirmation of extraterrestrial spacecraft. Instead, they highlight a continuing problem surrounding UAP reports: some observations remain unidentified even after being investigated.

Loeb believes those cases deserve serious scientific attention rather than automatic dismissal.

Mysterious Orbs Have Become a Major Clue

Among the phenomena discussed were mysterious glowing orbs. Loeb said reports involving these objects have emerged from US agencies including the FBI, with some sightings still lacking a clear explanation. He stressed that while some could potentially be drones, he believes others cannot be easily explained in those terms.

That uncertainty, he argued, should turn the investigation into a scientific detective story.

'We should look at it as a way for us to learn about new technologies,' Loeb said, challenging the assumption that existing physics can immediately explain every unusual observation.

His comments come amid continuing public interest in UAPs, particularly footage and reports involving objects displaying unusual movement, appearance or behaviour.
