Very probably, extra-terrestrial life, if any will be discovered soon, will be very unlike that.
From daily The Independent in Britain:
We will have definitive evidence of alien life in 20 years, Nasa chief scientist believes
Strong indications of life beyond Earth could be found within a decade
Wednesday 08 April 2015
The discovery of extra-terrestrial life, probably the most exciting event in human history, may well take place within most of our lifetimes, a high-ranking Nasa scientist has predicted.
“I think we’re going to have strong indications of life beyond Earth within a decade, and I think we’re going to have definitive evidence within 20 to 30 years,” Nasa chief scientist Ellen Stofan said on Tuesday, during a panel discussion focusing on the space agency’s search for habitable environments outside of Earth.
“We know where to look. We know how to look,” Stofan added, “In most cases we have the technology, and we’re on a path to implementing it. And so I think we’re definitely on the road.”
Sharing Stofan’s optimism, associate administrator for Nasa’s Science Mission Directorate John Grunsfeld said: “I think we’re one generation away in our solar system, whether it’s on an icy moon or on Mars, and one generation [away] on a planet around a nearby star.”
The Milky Way is “a soggy place,” Paul Hertz, director of Nasa’s Astrophysics Division, explained.
“We can see water in the interstellar clouds from which planetary systems and stellar systems form.
“We can see water in the disks of debris that are going to become planetary systems around other stars, and we can even see comets being dissipated in other solar systems as [their] star evaporates them.”
These estimates don’t even take into account the fact that alien life may be able to prosper in conditions different to those required by humans, e.g without need for water.
