A space mission from Earth lands on a distant planet called Bogo. As the astronaut began to explore the rocky planet, he heard what sounded like two people talking. Confused, he stepped closer to the source of the noise. It seemed the conversation came from behind a giant rock. He picked up the large rock and marveled at what he saw: two small green aliens. He started talking to them. At first they looked bewildered but then they took out a bread and ate it. Then they could immediately understand what he was saying and even speak back. He was surprised and then a galaxy came flying ..... he woke up, it turned out that this was just a dream, a beautiful dream and full of science :))
