A top Russian scientist expects us to come in contact with aliens in the next 20 years — and they’ll look a lot like us!

“Life exists on other planets, and we will find it within 20 years,” said Andrei Finkelstein, director of the Russian Academy of Sciences’ Applied Astronomy Institute.

Speaking at a meeting last month on the search for extraterrestrial life, Finkelstein said 10 percent of the known planets circling suns in the galaxy resemble Earth.

If water can be found there, then so can life, he said, adding that aliens would most likely resemble humans, with two arms, two legs and a head.

“They may have different color skin, but even we have that,” he said.

Finkelstein isn’t alone in his belief that we’re not alone. In March a NASA scientist caused controversy after claiming to have found tiny fossils of alien bugs inside meteorites that landed on Earth.

Richard Hoover, an astrobiologist, said filaments and other structures in rare meteorites appear to be microscopic fossils of extraterrestrial beings similar to algae.

Hoover claimed that the lack of nitrogen in the samples, which is essential for life on Earth, indicated they were alive “long before the meteorites entered the Earth’s atmosphere.”
