The water was clearer than usual, it seems that the storm had helped to clean it up, usually a lot of particles among minerals, algae and terraforming nanomachines, reduced the visibility at this depth.
Lucien advanced a few more kilometers in the submersible, observing how small blue-green algae began to grow attached to the underwater floor, which was mainly made up of rocks and quartz.
"Here it is", he thought when he saw it, the place that the computer of terraformation had pointed out to him, three pillars of rock were raised where it had happened, probably the impact was so violent that made the magma of the mantle sprout, in this region of the planet the crust was very thin.
It was possible to see a small bulge in the middle of the three pillars that indicated the place of occurrence of the event, it approached and took some of ours of the water, that immediately introduced in the unit of analysis, in effect LUCILE had not been mistaken, in fact they seem never to be mistaken.
-Have you confirmed my reading, environmental engineer Lucien Rivera -heard LUCILE's unmistakable voice, saying over the loudspeaker.
-Yes LUCILE, there is no doubt about your result, - he answered.
He extended the arms of the submersible and using the excavator, broke the layer of vitrified rock that covered the bulge, in the middle of the pillars, to take samples. There was a whole layer of material different from what would normally be found at that depth.
-Here is the cause, LUCILE -he said when he saw the results of the analysis unit-. This is a meteor.
-I already knew that, environmental engineer, -said the smug LUCILE.
-Yes, but this one in particular seems to have some bacteria of terrestrial origin, -he replied.
After Lucien's last visit to the planet, three hundred years ago, a relatively small bolide had crashed several kilometers off the northern coast of the continent, in a shallow region. Years later, LUCILE, after taking samples from the area, found the abnormal presence of bacteria that had not been planted on the planet.
The proliferation of humans in this sector of the galaxy, in its constant wandering through space, has left biological material dispersed in different places, and it was becoming more and more frequent to detect bacteria, algae and other forms of microscopic life, capable of surviving in the vacuum of space, which were transferred to previously sterile planets, after the impact of meteorites.
Now, life, once confined to Earth, was spreading unwittingly throughout the galaxy.
