Are all human beings aliens who immigrated from outer space?

The astrobiologist said that the first "seeds of life" came to the earth from 3.8 billion years ago. These microbes from outer space came to the earth with comets, then multiplied and evolved, and finally formed human life. His findings were published in the International Journal of Space Biology of Cambridge University. Evidence shows that the origin of human beings and all other life forms on the earth is related to the alien life that followed the comet to the earth. After the comet hit the earth, these microorganisms began to take root and sprout. Professor Vikramasin affirmed: "The evidence shows that we are all aliens, and we share the same cosmic lineage. Every time a new planetary system is formed, some microorganisms will travel to other planets with comets and then multiply and evolve on that planet. Therefore, human beings and other life forms on our planet are just one link in the huge chain of the entire cosmic system. " Professor Vikramasin also believes that life arrived from one planet to another billions of years ago, and the whole process of migration and reproduction lasted for hundreds of millions of years. But under this theory, it still can't explain how primitive life evolved. Since 1960s, Professor Vikramasin and his late colleague Huo Fred Hoyle have advocated the theory of "students". He said that astronomical evidence can absolutely support the view that all living things on earth did not originate from the earth, but from outer space. Although we don't know how primitive life came into being at present, once it came into being, it can be propagated in the universe. Professor Vikramasin said: "At the beginning of 20 10, we will announce that human beings may have alien descent, and it is also possible for life outside the earth to exist.
