“Oxygen flooded into the atmosphere as a pollutant, even a poison, until natural selection shaped living things to thrive on the stuff and, indeed, suffocate without it,” wrote evolutionary biologist, Richard Dawkins, in The Greatest Show on Earth: The Evidence for Evolution.

“Judging by the history of life on Earth and the possible futures we think we can see coming, it is indeed quite possible that most, or effectively all, civilizations in the universe are comprised of machine intelligences,” wrote astrobiologist David Grinspoon in an email to The Daily Galaxy.

Scientists have long speculated that Juptiter’s moon Europa has an icy crust covering a vast, global ocean –what Caltech’s Mike Brown describes as a “miniature Earth” ocean. The rocky layer underneath may be hot enough to melt, leading to undersea volcanoes.

Has life started many times of Earth? Could life as we know it today on our pale blue dot in fact be a second genesis? Could Earth’s original microbial life have formed four billion years ago, only to be destroyed some ten million years later during the age of Late Heavy Bombardment by massive asteroids sterilizing the planet? But perhaps some of this primordial “life as we don’t it” survived the 200-million-year barrage of huge objects followed by a second genesis of microbial life representing our form of life co-existing to this day with a “shadow biosphere” of Earth’s original alien life forms.
