The thirtieth:
Time to remember
Article published in February 2014

In some place, we living beings dwell.
We need a space to live in the material world. Let us consider some examples:
1.The atmosphere is the place where birds spend part of their time, and where many microorganisms live permanently.
2.Among the rocks, live several kinds of spiders
3.In the sand, crabs live. They spend their days in holes or moving side to side.
4. In the seawater, live many species of fish, plants, microorganisms and even the biggest mammal, the whale.
The list continues, but remember that these are material spaces (air, water, rocks, sand, etc.). However, in their materiality, they offer conditions that make like possible.
It is the case of the atmosphere. In the primordial times of our planet, it had no oxygen. Primitive forms of life enriched our atmosphere with this gas, allowing the existence of more developed forms of life, including ours.
Our material world is thus different than that one in Mars, despite many similarities between the two planets.
This is the base of the Gaia Theory: primitive forms of life transforming the material space of a planet in order to make possible the existence of more developed forms of life.
