In a conference at the International Paris Air Show (SIAE), the philosopher Étienne Klein and the sociologist Gérald Bronner answered the question: "Is the future of humanity essentially linked to the Earth? "
"Man is Terran before being human"
On the 219 exoplanets discovered by NASA's Kepler Space Telescope, 10 could be habitable. Good news, no? Yes, except that the closest of them is 40 light-years away from Earth. With the current technological means, it would take millions of years to reach it. Needless to say none of us will see a piece of exoplanet - except perhaps Walt Disney, who smarter than everyone else, has been cryopreserved. In short, we might want to go very hard, the physical limits are indeed there.
“We will only be able to leave Earth if we take it with us.” - Edmund Husserl
Physical limits or not, for Étienne Klein, the future of man can only be on Earth. "Man is Terran before being human. We could leave Earth, but we would lose our humanity", explains the philosopher. Because on Mars or elsewhere, it is impossible to exchange normally in a diving suit, to have a drink on the terrace or to take a dip in the sea. "What makes us humans, our way of being together, depends on the conditions of life on Earth. I don't think that desire is transportable, "insists Étienne Klein.

I share the conclusion of Etienne Klein:"Space is tourism. We won't go any further," explains Étienne Klein. Before concluding: "And then life in space, it's not funny at all."
