A well-known astronomer and top alien hunter claims that human life may have descended from Martian aliens. Seth Shostak, director of the Search for Extraterrestrial Intelligence (SETI) institute, says life on Earth could be a byproduct of what has been happening on Mars. He believes that a great collision of an asteroid and Mars could have caused dirt from the red planet to be flung across space and land on Earth.
"It's possible that billions of years ago, tiny bits of biology quit the Red Planet and infected ours," Shostak says. If that was the case, then every other life form here on Earth has its deep roots not in the old oceans of the planet, but rather in the extinguished seas of Mars, he elaborates. His claim is based on a theory called panspermia.
According to this theory, selected microorganisms could survive the space between planets. When the asteroid collided with Mars, Martian aliens such as microbes could have been flung to the planet Earth, landed on the planet's surface, then proceeded to grow and evolve. Shostak adds that scientists have estimated billions of rocks between an inch and a yard in size were involuntarily shuttled from the Mars to our planet in the early days of the solar system, the Daily Star reports.
He also says that Mars is thought to be wetter and warmer in its early days compared to its present environment. According to the Daily Express, it is not impossible to think that living things could have been spawned in Mars when no living creature existed on Earth. Because so many Martian rocks were catapulted into space, the probability that at least some would have come from an inhabited patch of Mars, is pretty high, assuming that there were Martian aliens inhabiting the planet.
