Abstract

In the report presented above, we analyzed the different data provided by the scientific community, from which we can deduce that the emergence of an interstellar civilization is highly unlikely due to the large number of exact factors that have to occur for the birth of a civilization of this type magnitude; for example, the exact planetary location that is suitable for life for a long period of time, the sufficient amount of resources for its development, stable environmental conditions, etc.

On the other hand, humanity is in the eighth step according to the great filter theory, which would mean that the most difficult obstacle to overcome as a civilization will be in the space colonization (step9) step in case the previous 8 have not yet been.

Space exploration technology is very recent, therefore inefficient, so humanity will have to wait several millions more years to achieve the colonization of the galaxy.

In the above it is talked about how the human being has never found a sign of an advanced life form from another planet and as mentioned it is quite difficult for it to happen due to the number of exact factors. However, it is too possible that they exist, this because on nearby planets like Jupiter, whose moon 'Enceladus' is capable of harboring microscopic life, it must also be borne in mind that human beings do not even know well the system in which we find ourselves. Living to say that it is impossible for life to occur on other planets is a rather ambiguous answer given that life itself on earth is a fact that is the result of various specific circumstances, so it is not at all unlikely that it will not occur.

On the other hand, it is possible that there are more civilizations and we have the same doubt that we have about whether there is more life in the universe, it is also likely that this life is simply microscopic or that it still has a long way to go. They have the same intelligence as us, although they touch on more paranoid topics, the reports of the so-called "UFOs" have existed for years even before the media such as radio existed, there are also theories that suppose that some of the fantasies beings like the chupacabra. Going deeper there are even testimonies from people who claim to have had contacts with strange beings, although again talking about this is touching conspiracy theories and talking about science fiction. In reality, there are many years left for human beings to colonize another planet or for another civilization to discover us.
