Aliens.
I believe in aliens from other planets. I believe they have visited us. And I believe they left soon after with tears in their eyes.
For I believe that if a species is capable of traveling through space they are intelligent enough to not destroy their world, or maybe they did and that’s why they had to leave. Either way, I believe they would be disgusted and sad at the way we treat our mother earth and therefore would leave without saying “Hello”.

Help me grow. Please give me feedback.
