What are things not available on moon?

Answer 1

To be a little specific it's the enough 'gravitational force'. This is primarily responsible for moon's lack of atmosphere. This adds to lack of oxygen, the friendly atmosphere, water, and so on...

Answer 2

The moon lacks the atmosphere needed to sustain life, leading to no air, water, or food sources available naturally. Additionally, there is no magnetic field on the moon, resulting in high levels of radiation exposure from the sun. Lastly, there are no natural weather patterns, leading to extreme temperatures fluctuating between very hot and very cold.
