Yes, and it's still there.
It's just ice though, and it never flowed. It's from frozen asteroids hitting the moons surface.
There is no liquid water on the moon. There is some evidence that there is frozen water.
There is no evidence of any water on the moon, fresh or otherwise.
Evidence of frozen water are near the poles
There is some indirect evidence of frozen water on the Moon, no one can be sure of how much exactly.
No, Earth's moon does not have a hydrosphere. There is no evidence of liquid water on the moon's surface.
There is no conclusive evidence that there has ever been water on the Moon. However, theories suggest there may be water trapped in ice in hidden craters of the Moon.
some moons show evidence of ice or water that lie deep beneath the surface
There is no evidence to suggest that water on the moon contains protein. Water present on the moon, typically in the form of ice, lacks the necessary components for proteins to form. Proteins are complex molecules comprised of amino acids, which are not found in abundance on the moon.
This is correct. The moon has no atmosphere. This fact, along with the fact that thus far, no evidence of water has been found on the moon, contributes to the reason why rock erosion does not occur on the moon.
evidence of ice.
No, a rubber dinghy cannot be used on the moon as there is no water or atmosphere to support buoyancy or movement. The lack of gravity and extreme temperatures on the moon would also make it impractical for any kind of water-based activity.
There is no scientific evidence to support the claim that birth control is intentionally being added to the water supply.
