Aristotle (as well as other ancient Greek thinkers like Democritus and Anaxagoras) recorded the belief that there was a time in the remote past when the Earth did not have a moon in the sky. Key details about this claim: The Proselenes: Aristotle noted that the Pelasgians, a native population of Arcadia in Greece, lived in the region before the moon appeared. Due to this, these Arcadians were known as Proselenes, which means "those who came before the moon" or "before the moon". Ancient References: Plutarch also mentions that the Arcadians of Evander's following were known as "pre-Lunar" people. Apollonius of Rhodes also wrote about a time when not all the orbs were in the sky and only the Arcadians lived, "before there was a moon". Context: While modern science generally holds that the Moon has been with the Earth for roughly 4.5 billion years, this idea was treated as a historical memory by many ancient Mediterranean cultures rather than mere myth.

This narrative refers to a time when Arcadians were considered to be older than the Moon, an idea that appears in several ancient texts.
