Life exists on other planets and we will find it within 20 years,” said Adrei Finkelstein, director of The Russian Academy of Science’s Applied Astronomy Institute . Finkelstein was speaking at an international forum on the search for extraterrestrials. He added that 10% of the planets circling suns in the galaxy resemble Earth. “If water can be found there, then so can life,” he added. On a final note, he predicted that aliens would probably look like humans, with two arms, two legs and a head.
