Aliens would make his day

Science-fiction writer Arthur C. Clarke listed three wishes on his 90th birthday: for the world to embrace cleaner energy resources; for a lasting peace in his adopted home, Sri Lanka; and for evidence of extraterrestrial beings.

“I have always believed that we are not alone in this universe,” he said in a speech to a small gathering of scientists, astronauts and government officials Sunday in Colombo, Sri Lanka.

Humans are waiting until extraterrestrial beings “call us or give us a sign,” said the British-born author of “2001: A Space Odyssey.” “We have no way of guessing when this might happen. I hope sooner rather than later.”
