my theory: the universe is incomprehensibly huge. we (earth) are just a grain of sand on the beach that is the universe. our galaxy is among billions of others. the chances that there are other conditions suitable for life beyond our own are incredibly likely think about this: our sun is our only star in our solar system. the stars we see at night are in our own galaxy. among the billions of other galaxies exist billions of other stars like our sun. what are tha chances that one of those trillions of trillion of trillions of stars has an orbiting planet like our own?
