Is there alien life?

For centuries mankind has been asking the question, ‘is there alien life?’  Books, movies, paintings, and numerous TV shows continue to depict evidence of aliens.

Scientists who generally are assumed to be the smartest people on earth are divided on this issue. Even astronauts who have into space are not sure about alien life. Those who believe that alien life exists state that we humans are just too arrogant to accept the fact that aliens may be sharing the universe with us.

Some scientists suggest that that the earth will one day die out and life may evolve somewhere else in space. They believe that life is constantly dying and evolving in space and the reason we do not have evidence is because the distances in space are vast.

This type of thinking is more common today than ever. There is a general belief that there are worlds out there that could give rise to life. The universe is enormous and bigger than all the number of humans who have ever lived on earth. In this wide expanse it is inconceivable that another form of life does not exist. To state that the earth is the only planet with life in this vast cosmos is highly egocentric.

However, other scientists have dismissed these hypothetical arguments about alien life as nothing more than too much ‘star trek’ mania. William Borucki, a renowned scientist with NASA, whose research team has discovered several new planets says, "Up till now, it was just an intellectual question. It isn’t anymore. There could be 10 billion civilizations or none. The evidence certainly is none." According to Borucki, "The evidence says no one’s out there."

Finding alien life will be a huge step for astronomers. We still have difficulty getting the Space shuttle up into space a few hundred miles above earth with a great deal of difficulty and so a journey millions of miles is certainly going to be an enormous task that will also be prohibitively expensive. So far our best telescopes and spacecrafts that have ventured into space have found no evidence about any form of life.

Perhaps there is alien life but whether we encounter it is very unlikely. For those who are desperately seeking aliens, perhaps youtube will help satisfy your curiosity.
