The Astronomer Royal has asked “cranks” to stop writing to him about their alien experiences, insisting any extraterrestrials would more likely be an electronic entity than a little green man.
Professor Lord Rees added that aliens would be unlikely to be “flesh and blood” and “could be a million years ahead of us”.
The 79-year-old, a former president of The Royal Society, urged anyone wanting to inform him of an extraterrestrial encounter or alien abduction to write to each other instead.
