Andy Weir: Contact with Alien life would be almost impossible, everything would be completely different. Will they be able to tolerate our atmosphere? Their number system would probably be different as base ten doesn't actually have any scientific backup, how would that affect the way they view the world? How would their friendships be formed? What phrases would be interchangeable and how would that match their worldview? How would our relationships with them be formed? What about non-verbal signals? How would they see or hear? How would this be affected by their environment? How would this affect the way we talk to them? What about small and specific customs? What inconsequential things do humans have strict rules around?
