Aliens exist?

Search continues..

One of the exciting and mystical topics on earth is “life on other planets”. Do we really have life elsewhere than earth? We still have no answer for it. But many of the scientists and astronomers believe the possibility of life away from home planet.

The NASA (National Aeronautics and Space Administration) is searching our solar system for the existence of life constantly. The question started excitement among the people may be because of the movies. There are so many movies built and being built around the world using the aliens as prime theme for them. Aliens are the creatures from other planets than the earth. The rumors about the alien spaceship foot marks on the earth add fuel to the fire. But none of these rumors could prove truth among them. These are facts that made the world think about the existence of life in space.

There are few parameters to be considered before making any planet suspicious for life on it. The basic parameter on which basis life may exist is water. Earth, filled 80% of it with water, is the best example for how water so important for life. So far we could find two planets with very good quantity of water. One of them is Europa. It is covered with subsurface ocean below icy crust. Scientists are keen on it to search life on this planet.

If searching life in space is one issue, there are also scientists who warn that we are possibly inviting danger to the earth by sending signals into space for life. If there is complex life exists in space and if they find our signal from earth, it leads to the question of existence of the earth.

As nobody is so sure about the life in space, until we find an answer to it, the issue will be as exciting as it now to our next generations.
