Don’t feel like reading? Watch this 6 minute video: Are We Alone In The Universe?
This is a difficult question to answer…especially from a scientific perspective. There is absolutely no concrete evidence of extraterrestrial life, let alone “intelligent” life, but that doesn’t mean it’s not out there. Some estimations amount to 10 million billion intelligent civilizations in the observable universe. And that’s just in the parts we can “see”!
The well-known, Carl Sagan, famously said that the worlds in space are as numerous as the grains of sand on Earth. Well, if this is true, then where are all the aliens? This is the Fermi Paradox…to which there is no answer, but there are MANY possible explanations. Here are a few:
- We are extremely rare
- Our technology is underdeveloped/other civilizations are not broadcasting their signals
- They’re here! We’re just too dumb to perceive them (The Zoo Hypothesis)
All in all, even if we do find intelligent life out there, who says that we’re going to be able to communicate with them? Plus, we physically can’t even imagine what these other species would even look like, so how can we define our search if we don’t even know what we’re searching for?
Personally, I think we’d have to be narcissistic and a little bit ignorant to believe that we are the only intelligent beings to ever exist. I mean, as of today, we have explored less than 5% of the oceans on Earth, so just imagine the possibilities for the universe.
