A Harvard astrophyicist has said only one type of alien could reach earth after reports of alien sightings on earth.
Discrediting anecdotal sightings of aliens roaming the planet, Avi Loeb said its highly unlikely any “biological creatures” could ever reach earth.
Loeb said during an appearance on GB News: “It would take about a billion years to cross from one side of the Milky Way galaxy to the other.
“Given that, I don’t think any spacecraft that would arrive to us from another star would carry biological creatures.”
Images and videos of supposed alien sightings are common across social media, with amatuer sleuths believing they have spotted creatures that could be from beyond our world.
The US Department of Defense released images of supposed alien sightings in 2017, with the mystery of what was captured by US Navy pilots still unsolved today.

But Loeb said that if any extraterrestrial ever lands on earth, they would most likely be a creation of artificial intelligence.
He said: “They wouldn’t survive the journey being bombarded by very energetic particles in interstellar space for so long.
“It’s more likely, if they are autonomous, they have an artificial brain, artificial intelligence.
“We have already developed that on Earth, we haven’t launched it to space, but that would be the next step.”
Ziven Havens, the policy director of the Bull Moose Project, has agreed with Loeb.
He said: “There is a possibility that AI will open up space travel both for manned and unmanned vehicles by reducing costs and increasing safety.
“The possibilities are truly endless, and that makes the future of AI more exciting.”
Samuel Mangold-Lenett, editor at The Federalist, said AI could be used to help spacecraft survive the harsh conditions of space.
He commented: “AI can be used to [run] complex complications in short periods of time.
“So, on the surface, AI could be used to chart courses, figure out ideal weight loads and anything else related to space travel that requires complex math.
“It could also be used, as we’re seeing with medical science and agriculture, to install and operate systems that preserve and maintain life in harsh or even unnatural environments.”
