Such allegations are made from time to time. Stephen Hawking claims this and we are confused. After all, we cannot say that it is impossible. But we think it's possible and we can't be sure. Claims without proof are meaningless. We need to see it with our own eyes or see something as evidence. Other than that, it will always remain a vague claim for us.

Professor Avi Loeb, who is also close friends with Stephen Hawking, shared with the press that aliens from extraterrestrials landed on Earth on an autumn day in 2017. He said that the aliens who landed on Earth in October came to Earth in a boat and used light to accelerate. According to Hawking, aliens have already visited our world.
