The chances of finding human bones on the Moon are essentially zero. As far as our current scientific knowledge goes, there are no human remains on the Moon. The Moon is an airless and lifeless celestial body, and no human beings have ever lived or died there.
The only human-made artifacts on the Moon are the remnants of the Apollo missions, such as spacecraft, lunar modules, rovers, and various equipment. These artifacts were left behind by astronauts during their visits to the Moon between 1969 and 1972. However, human remains were not part of these missions, and there are no reports or evidence to suggest that any human bones were brought to the Moon.
It's worth noting that space exploration and the potential for future human habitation on celestial bodies like the Moon or Mars raise ethical considerations and discussions regarding the treatment of human remains in space. However, as of now, no human bones are known to exist on the Moon.
