" Have you ever thought about the existence of life beyond earth..?? "
" Does there exist an advanced civilization in universe, which is better than humans..?? "
" If so, have they achieved the speed of light..?? "
The Universe which ages 13.8 billion years spreads across billions and billions of miles. It has got a large number of galaxies which has trillions of stars and planetary systems. But there is not even single evidence of life anywhere. Though our scientists have developed so many types of equipment and devices to detect any kind of data outside the earth, there are no pieces of evidence to prove the existence of life outside earth. Generally, we refer to this life as Aliens (those who exist outside the earth). Aliens can be in the form of microorganisms like bacteria or viruses or it can be as complex as humans.
