As Arthur C. Clarke once famously said, “Two possibilities exist. Either we are alone in the universe or we are not. Both are equally terrifying.” This quote is relates in a very basic way to the Fermi Paradox. The paradox is that through the Drake Equation and the sheer size of the universe, there should be other alien lifeforms, however we have no good evidence of their existence. There are a few solutions to this that we have studied, and that is either we are truly alone, there are other lifeforms out there that have purposefully remained hidden from us, or other civilizations destroy themselves too quickly to communicate with other civilizations. While these three are probably the most likely scenarios, I have a more interesting explanation.
I personally believe that there is life out there, there just has to be based on how large our universe is. However, I believe that these lifeforms are much more advanced than we are, as they have probably been around longer than we have. Because of this, I believe that a solution to this paradox is that there are other lifeforms in existence, but we will never find them because they created us, and are studying the development of basic life on a perfectly placed planet in a solar system through an advanced simulation. They created this sandbox universe for us to see how long it takes for a civilization like their own to develop, with no other interference from alien life forms. They are simply using us as a science experiment to study the formation of life, and have purposefully made us the only ones in the universe, for now. While this may seem crazy, I doubt there’s any evidence that can disprove this theory, and personally I just think it’s a cool way to explain why we are alone in the universe (Source of information: Wikipedia).
