Aliens May Have Visited Earth Already But We Missed It, NASA Scientist Says

Silvano P. Colombano, a scientist at NASA Ames Research Center,  stated in a new research paper that Earth may have already been visited by Aliens, but humans may not have noticed. He proposes that intelligent life may not be what we think it is and may not probabaly use the traditional core building blocks of that humanity is familiar with, such as carbon.



According to Silvano, researchers must go back to our most valued assumptions and study the idea of diverse characteristics as well as the likelihood that interstellar travel is already possible for extraterrestrials.

In his research paper, Silvano wrote, “I simply want to point out the fact that the intelligence we might find and that might choose to find us (if it hasn’t already) might not be at all be produced by carbon-based organisms like us. So, if extraterrestrials are not carbon-based, what does that do to our assumptions about what to look for? Well, a lot. Our typical life-spans would no longer be a limitation (although even these could be dealt with multi-generational missions or suspended animation), and the size of the ‘explorer’ might be that of an extremely tiny super-intelligent entity.”

He also pointed out that the alien life may have made sense of the technology that people cannot even understand yet, for instance, conceivable interstellar travel. On the off chance that we obtain another set of assumptions about what kinds of higher intelligence and innovation we may find, a slice of those marvels may fit obvious theories, and we could start some genuine analysis.

Colombano clarified, “Considering further that technological development in our civilization started only about 10K years ago and has seen the rise of scientific methodologies only in the past 500 years, we can surmise that we might have a real problem in predicting technological evolution even for the next thousand years, let alone 6 Million times that amount!”
