If we do assume there is intelligent life in places other than Earth, where might they be? Though scientists last century thought the planet Mars might be a good candidate, and some even thought they detected a huge canal system stretching across the planet, recent probes sent to Mars have failed to detect even bacteria-like creatures, let alone a civilization capable of producing a flying saucer. With the rest of the planets in our solar system seemingly too hot or cold, the best hope for intelligent life seems to be across the void of interstellar space in other parts of our galaxy.
In an attempt to detect intelligent life beyond our solar system researchers have conducted a number of SETI programs trying to use radio waves to detect the existence of other civilizations. So far no SETI program has been successful in finding intelligent life, but there are millions of stars in our galaxy alone that might have planets that could harbor life and carefully looking at each one of them will take a long time.
Is there intelligent
life on other planets? Have they visited us on Earth? Are some UFOs alien
spaceships? Or are there other explanations for saucers in the sky? Nobody
has final proof one way or another. We need to keep open eyes and open
