Who has ownership of the moon?

Could you please clarify the legal status of ownership over the moon? Is there a universally recognized authority or entity that holds exclusive rights to the moon, or is it considered a common resource available to all nations? Additionally, have any international treaties or agreements been established to govern the exploration, use, and potential development of the moon's resources? And if so, what are the key provisions and implications of these agreements for nations and private enterprises seeking to engage in lunar activities?
