The Search for Extraterrestrial Life

Powerful Essays
Abstract: Scientists claim that other life forms do in fact exist based on probability. The conditions necessary for life are likely to be present on various other planets. Signs of possible life have been found in material from outer space. Much research has been dedicated to proving the existence of life on Mars. SETI is a program entirely dedicated to finding and establishing communication with extra terrestrials. If other life forms are found, communication with these beings will be a difficult task. Laws to protect humans from the dangers of extraterrestrial beings are already in effect. Although contact with alien beings has not yet been made, technology today may make it a reality in the near future.

Often these beings bear strong resemblances to human beings, with slight alterations. When imagining what exactly an alien would look like, we are biased to believe that extraterrestrial beings are little green men with antenna's protruding from their head and they fly around the universe in huge spaceships. However, these little green men are figments of our imagination, as true life it has yet to be proven that life does, in fact, exist elsewhere in the universe. Scientists have tried for many years to find extraterrestrial life, unsuccessfully. Yet their work has not been completely in vain. There is evidence that life can and possibly does exist on other planets. Our job is to find direct proof of this hypothesis and to attempt to establish communication with these foreign beings.

... verified). However, the way society perceives extra terrestrials may be completely not accurate. We may not be able to imagine the forms or types of life that exist outside of earth. They may bear little or no resemblances to our own human race. Hopefully, in the near future, our work will pay off and we will find absolute proof of the existence of extraterrestrial life. Five hundred years ago we were still exploring the limits of the Earth. Who knows what findings we may incur in the next five hundred years.
