Without the tides, there would be no land-based life, including people.
According to research, the Moon's creation allowed life to originate on Earth. Its gravitational force on ocean tides helped create life-giving primordial soup.
Predators use nighttime darkness and moonlight to prey. Without it, prey would flourish and many predators would go extinct.
The tilted Earth and the Moon produce four separate seasons. If there were no Moon or if it were 10% further away, Earth may topple.
If the Earth tipped 90 degrees, the climate would change. Without the Moon, Earth's tilt would be erratic and wild, generating no seasons, harsh weather, and ice ages.
