The recipe for life from other worlds




We are getting closer to finding life outside of Earth, because we are getting closer to places where liquid water exists and also has the elements that we assume are essential for life to emerge. We could be wrong or something is missing that we do not know. in the recipe that we believe is essential for life to emerge and that life on earth is something much rarer than we believe, but if we are right, we are then approaching worlds that do have liquid water and that do have those elements such as the Saturn's moon Enceladus or Jupiter's moon Europa.


In the case of Jupiter's moon Europa, which is almost the size of our moon, that is, it is a large body, in that case it would have a huge global ocean with much more water than all the water that exists in the oceans of Jupiter. the earth and it may also have had that global ocean for billions of years of existence, therefore if life emerged there it had time and space to evolve into amazing life forms, pay attention to this detail.




If in the same way we are talking about forms of life as we know it, because we do not have another recipe and we are also talking about the basic elements for life, but of the only recipe we have we also only know one evolution and although there are structures like that of a jellyfish or the limbs that can arise in many animals because it is a basic element to be able to move in certain circumstances or the fins that are another basic element, it is basic engineering of nature, but removing those elements we only know one type of evolution.


An evolution that has taken billions of years to reach beings like us, but we do not know how fast it can go in other places, in other places perhaps evolution will get stuck and not go beyond the bacteria type or it could be the opposite. , that it evolves much more rapidly and that in just a few hundred million years complex animals emerge, is another of those details that we do not know because we have no clues nor do we have evidence, which is why it is important that one day we find life outside of Earth .


Because then we would have a clue as to whether this recipe we have here is the basic one for life to form in other places, and the other question is how quickly nature can evolve, how quickly complex beings can emerge.

Apart from the moon Europa which may have had a lot of time to develop life, there are other places, some very well known; We cannot yet rule out Mars as a place where life does not exist, we cannot yet label it a Dead Planet, because Mars had water for at least several hundred million years and also at the same time in which life emerged. on Earth and it is possible that Martian life forms continue to exist in aquifers or humid areas under the soil or under the polar caps in the same way that here on Earth there are colonies of microorganisms that can live inside the planet in isolation for thousands of millions of years as demonstrated recently with a discovery in South Africa.
