Space has enthralled human beings since times of old; ancient civilizations weaving their history through star clusters, medievals looking up to planets and wondering what other lives exist a stone’s throw across the sky.
…Okay, but to say it in a way that doesn’t sound like the beginning of a sci-fi novel, throughout human history many have puzzled over the possibility of alien life. I am no different. I have a “I want to believe” pin and an alien patch on my backpack, for goodness sake!
The idea of aliens has only picked up for me in recent years. There was no pivotal occurrence that happened in my life that directed my attention to them. One day I was ‘normal’ (take that with a grain of salt, since I’m talking about myself here), and the next I was marathoning videos of alien evidence on YouTube and spelunking through conspiracy theorist forums online.
I was completely taken with it! The concept of interplanetary beings—I couldn’t stop thinking about it. Really, the idea of alien life makes quite a bit of sense.
Scientists estimate that roughly two million galaxies exist, and in multiplying that by the ten million stars that tend to appear in each galaxy we find that there is somewhere around 10^19 stars in the universe. From data collected on the Kepler Space Mission, scientists said that there may be as many as 40 billion Earth-sized planets orbiting in the habitable zones of sun-like stars or red dwarfs in the Milky Way alone. Eleven billion of those planets may be orbiting sun-like stars.
A crazy cocktail is required to create life. Water, a carbon base and some form of energy; they have to align just so with any given planet’s temperature, pressure, etc., to kick start even a single-called organism.
But something the size of an amoeba is still alien life—and with all the numbers running through space, who’s to say it hasn’t already happened? It may be a while before we can communicate with any alien life, but the numbers are on the side of it at least existing.
