No one know yet if we are alone in this universe. Did life evolve somewhere else? Are we truly special? Maybe just the first? Many try to answer this riddle. I just find it interesting, that often people don’t talk about the many “things”/”coincidences”, that we survived, to even dream about this question. The following is a growing list to collect these challenges.
- Planet in a habitable zone
- Earth’s magnetic field
- A lot of water
- Solar System in a calm area of the galaxy
- Slow burning star
