As the media fills the web as NASA shares the discovery of 7 planets outside our solar system. The news of this planets is that most of them have water which means a possibility of developing life.
The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water – key to life as we know it – under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.
Ancient greeks already said that water is the beging of everything that exists. As the first greek philosopher, Thales, thought of the αρχε (beginning) of all things is the water. Water is the main element we need to live, all living things share this necessity and dependence to this principle. It decides who lives and dies, water in excess drowns us, as the lack of water makes us dehydrated. It is what unites all beings.
This great discovery doesn’t mean that there is life, as we know not only water guarantees life, but a couple of elements more to consider life if it has the basic qualities considered in living beings: to be born, to grow, to reproduce and die. If life is found there we must not ovibliate this basic principle.
