The possibility of intelligent life beyond Earth has intrigued humanity for centuries, but recent discoveries seem to prove that we are edging closer to the discovery. Findings such as Earth-like exoplanets, the past existence of water on Mars and habitable moons in our solar system suggest conditions for life are not unique to our planet. However, there is yet to be any concrete evidence of the existence of aliens, but scientists believe it will come – and potentially as early as next year.
