Language has existed on Earth for about one million years beginning with Homo erectus, says linguist Daniel Everett (see video below), which begs the question: do sentient beings with language exist elsewhere in the Cosmos? In December, 2020 ex-CIA Director John Brennan said it was “presumptuous and arrogant” to believe there are no other forms of life than the ones on Earth, referring to the videos released by the Pentagon of US Navy sightings of UFOs.
“Homo naledi seems very similar to modern humans in ways that we think reflect its behavior,” wrote paleoanthropologist John Hawks, Vilas-Borghesi Distinguished Achievement Professor at the University of Wisconsin-Madison in an email to The Daily Galaxy. “It had hands that clearly were adapted for toolmaking and tool use. It had teeth that seemed adapted to the kind of high-quality diets that we have thought were a pathway to the evolution of large, humanlike brains. Even though its brain size was around a third the size of ours, it survived for a million years or more in Africa where much larger-brained species lived, including early modern humans.”
Could one of Earth’s most intelligent species be an alien, ‘seeded’ on the planet by an interstellar genetic code? Scientists speculate that the clue might be found in the ancient precursor to life: RNA.
NASA’s mantra is that we should be open to search for life not as we know it. Arik Kershenbaum at the University of Cambridge and author of The Zoologists Guide to The Galaxy believes that “the bizarre and the unexpected – aliens made of gas, or with properties and abilities we’ve never dreamed of – are always possible, but they will always be rare.”
