In the film Prometheus about traveling to the moon of a distant planet to find our creators, Shaw and Holloway make a presentation on their research to the crew. They claim they seek answers to the age-old questions of where we came from and who we came for life on Earth. They claim our DNA was “engineered” by the same advanced alien species they seek on the moon called LV-223.
Immediately the biologist on the crew objects, saying that they are discounting three-hundred years of Darwinism.
No, they are not at all. The aliens did not seed the planet with alien babies, they allegedly seeded Earth with DNA that we assume was combined into microbes and helped to evolve life as we know it. This would demand all the Darwinian principles of evolution. In this case evolution on Earth did not create DNA itself, the backbone of life, just the life derived from it.
It turns out there is hard scientific evidence to support the panspermia hypothesis. One line of evidence lies in our biological evolution, and especially that of microbes as the precursors to complex life. It suggests that microbes with DNA came from off-planet to kick-start life on Earth. Another line of evidence shows that our genetic coding itself, in all probability, was, in fact, designed and bears signatures saying so. Our genetic coding boasts nine prime numbers as a signature, a statistical chance of being natural at one in ten trillion. In other words, its ten trillion to one that we were genetically engineered. When we combine the two, that our DNA arose from sophisticated genetic engineering, and that it our microbe evolution suggests “alien” donors of DNA to take the lead in creating life, then we can make a good case that we are of alien origin.
Another line of documented evidence that we are not alone lies with a very small interstellar visitor that zipped through our solar system in 2017. We only had eleven days to gather data on Oumuamua. It was thin, showed evidence of being metallic, was propelled by a force assumed to be the sun, and had so many unique properties that Harvard astronomer Avi Loeb said that, rather then a comet or asteroid, it was a work of technology. According to Dr. Loeb, it was most likely some sort of light sail. His hypothesis and book on the subject shook up the scientific world.
