Scientists Vladimir I. shCherbak of al-Farabi Kazakh National University of Kazakhstan, and Maxim A. Makukov of the Fesenkov Astrophysical Institute believe that human DNA was encoded with an extraterrestrial signal by an ancient alien civilisation, Discovery.com reports.
They call it "biological SETI" and the researchers claim that the mathematical code in human DNA cannot be explained by evolution.
"Once fixed, the code might stay unchanged over cosmological timescales; in fact, it is the most durable construct known," the researchers wrote in scientific journal, Icarus. "Therefore it represents an exceptionally reliable storage for an intelligent signature.
"Once the genome is appropriately rewritten the new code with a signature will stay frozen in the cell and its progeny, which might then be delivered through space and time."[Research paper]
The scientists also claim that human DNA is ordered so precisely that it reveals an "ensemble of arithmetical and ideographical patterns of symbolic language".
Their research has led the scientists to conclude that we were invented "outside the solar system, already several billion years ago".
The thesis supports the hypothesis that Earth is the result of interstellar life forms distributed by meteors and comets.
So if we are just vessels for alien communication, exactly what kind of secret message are we carrying in our DNA?
And if we were the creation of aliens, who created them?
