Did life ever exist on the moon? Maybe! Have scientists found evidence of life on the moon? Definitely not.

Why are we talking about this? A new paper was published online today (July 23) in the journal Astrobiology with a thrilling headline: "Was There An Early Habitability Window for Earth’s Moon?" Its associated press release had an even more exciting title: "Researcher sees possibility of moon life." Wowza! This is genuinely cool stuff. But it’s important to understand what it’s really saying and what it’s not.
