Neil Degrasse Tyson, a prominent astrophysicists. In one of his many interviews he mentions that our universe is so unimaginably huge, that it is ignorant of us to believe that we are alone in this universe. I agree, we only know as much as we tell ourselves and many people choose to accept the reality that they have always known, but not I. How can we be certain that our planet earth is the only planet in the billions and billions of other planets that exist, to hold life. Maybe it’s not humans, maybe it’s a different type of organism, maybe it is something that developed in a way that would allow it to survive in its host planet. Maybe they are more advanced than us. Maybe they are testing and experimenting on us to see how a human acts in certain circumstances just as we test on animals such as mice who have no idea that a higher being is testing on them. Maybe we’re one of the many planets to harbor life just as it happened on other planets billions of years ago and now all we see of them are remnants. Maybe they experienced a huge catastrophe that wiped out life. Maybe the star they orbited finally exploded just like ours will one day. I mean isn’t it true? Isn’t it arrogant of us to believe we are alone in the universe? Just because we don’t understand it, doesn’t mean it’s not true.
