It all starts with a curiosity; The levels of Panspermia.

The theory of panspermia has several levels, there is a basic one that says that certain elements that are essential for the development of life did not originate on Earth, they had to come from space, that's how it is. practically yes. Almost all astronomers agree that comets and asteroids were the ones that brought certain elements that have to form in the cold part of the system, in our case the solar system, because in the warm part they cannot condense, they cannot form and those elements are essential for life.

Water, for example, in the part where the Earth is, it would be very difficult for water to exist at the beginning of the solar system, so it had to come in comets and other organic molecules, but there is a higher level that would be that of life forms that arrived within comets, asteroids and that gave rise to life. That is not yet confirmed and it is difficult to confirm it for one reason, because we know that all life forms on Earth come from a single primordial being, because we share a basic series of DNA with all beings on Earth.

That basic DNA is in everyone, if other forms of life had come from space, there would have to be several different ones, several different lottery combinations, several different combinations of life and we do not see that, unless, be careful, there is only one possible combination for life to arise, which could also be an explanation of how rare life is on Earth, in that case, also if we find life outside of Earth, for example, on Mars or on the Moon Europa, it could be that it also shared that basic DNA, that basic genetic code. with us.

All this, the hard panspermia, the elevated one, that of life, would not explain the origin of life, it would simply transfer it to another place.
