Why do some scientists say that the moon may have been important for the evolution of human life?

The moon is large and is close enough that it is able to reduce the amount of variance in Earth's tilt. Long-term evolutionary theory requires that organisms have a healthy environment to survive for prolonged periods of time, with normal seasons and gradual large-scale tweaks. By keeping our planet's tilt stable, the Moon allowed the Earth to keep those conditions.
