Multiple Choice
Is a planet with a large, nearby moon more likely to evolve life than a planet without a moon?
A) No. There is no reason to believe the existence of a moon has any effect on the evolution of life.
B) Yes. A planet almost certainly must have liquid water to evolve life. A moon will raise tides, which can help to wash minerals into the water where it can provide a rich mixture conducive to the evolution of life.
C) Yes. A moon can help shield a planet from impacts which could destroy life in its early, formative stages.
D) The gravitational pull of a moon can help a planet establish a rhythmic day/night cycle which is important for the evolution of life.
