Is alien migration evolutionary? Science?

Seeing this question reminds me of a movie "Prometheus", which describes that the origin of human beings is due to the decomposition of DNA caused by engineers swallowing black water, but after falling into the water, a piece of DNA splits and recombines into cells, and then human beings appear after hundreds of millions of years of evolution.

The origin of mankind has always been a mystery. According to Darwin's theory of evolution, humans evolved from apes, but in modern times, more and more people have doubts about the theory of evolution. So now many people suggest that human beings may have originated from outer space, and their ancestors were immigrants from alien civilizations on earth.

Some people have put forward some scientific basis for this, such as human physique and physiological structure are not suitable for the earth's environment at all, human beings can't stand strong light and are deeply troubled by gravity, etc., all of which indicate that human beings probably didn't evolve on the earth, and may be brought by alien civilization.

There are also many ancient legends of alien civilizations visiting the earth in the world. Humans may also be a combination of terrestrial creatures and aliens.

In a word, it is not impossible for life to come from aliens, but it is possible.
