Queen Elizabeth's space guru is frustrated with people reporting that they have been abducted by aliens.
Astronomer Lord Rees of Ludlow thinks that aliens could exist but isn't always convinced by those who save they have had close encounters with the little green men.
Rees - who is The Queen's official adviser on outer space - said: "I get letters from people who say they have been abducted by aliens, they have met them.
"I respond with cynicism to such letters by saying: 'Is it really likely that if the aliens had made a huge effort to get here would they just have met one or two well-known cranks and gone away again?' It seems unlikely.
"So I tell these people to write to each other and not to me."
