According to Darwinian theory, life on earth has evolved from the same common ancestors through the process Darwin called natural selection. We haven’t found sufficient proof regarding ‘same ancestors’ from whom we have all evolved. Some says that life has started here on earth as a result of chemical process on primordial elements while other suggests that life on earth has originally came from other planet from other solar system. We are still not sure whether there is any form of life available on other planet in the Universe.
Frank Drake, a famous astrophysicist who founded SETI programme, devised now famous and controversial Drake equation in 1960. Using this equation, one can find our chances to find any extraterrestrial life or to check whether there such life exists or not in the universe. Within scientific community, considerable disagreement on the values of most of the parameters for the equation exists, and hence, we have no clear value for our chances to communicate with civilised communities within our galaxy.
It is fascinating to think that what if the life on our planet is the only unique creation of the universe and no other form of life exists anywhere in the universe. If this is true than we are special, each and every other species on this planet are special because it took nature millions of years to form life as we see it now. It will be our responsibility to preserve life on earth because we as a human are the most intelligent species and hence we are more responsible to take care of our planet.
Thinking about other possibility, what if there is an intelligent life exists somewhere, may be in our galaxy or in other galaxy? Can we be able to communicate with them in our lifetime? By looking at recent technological advancements in radio telescope and astronomy in general, I don’t think that right now we have that much capability to probe in the distant galaxies or to understand signals from aliens if we are able to capture any.
