WHERE do we come from? Where do we go? Personally, I am more interested in the first one than the second. The future is still to decide and to become. I feel more attracted by the past because it is tangible, demonstrable. Our history is a succession of success and errors, of calmness and tempests that work in a cyclic way. But there is something in the past that impassions me. Where do we place the beginning of life? And who were their true main characters? Little by little, one realizes that the answers to all these questions are right in front of us. Just as to every disease supposedly has its own cure, just the same, every mystery has its explanation if we know how to look for it well, in the most unsuspected corners of our own planet. In an article of the National Geographic discovered that the Geomicrobiology Lab of the department of Geoscience of the University of Pennsylvania, USA, Jenn Macalady, is analyzing the chemical compounds and the ways of life that populate the so-called Bahamas Blue Holes. They are submarine caves in the Bahamas that simulate what could have been the land before the invasion of oxygen. It is believed that life on earth began 4 billion years ago and only 2.5 billion years that oxygen appeared on the planet. During the next 1.5 billion years the life on earth was based in lathe beings that were ignorant of the use of the oxygen as a source of energy itself. Because of conditions, these Blue Holes are the perfect ecosystem to study how life could have existed without oxygen and to solve many doubts of the beginnings. But it also opens a wide door to possible explanations to assume that the absence of oxygen does not limit the existence of life for us, not even in each and every one of the million planets that exist in the universe. At the end studying the past we create our future. What's magical of all this is carrying out an investigation over something we do not know, because it brings us closer to the true mystery, which is at the end what we feel attracted to, to the unknown.
