A primitive stone tool that appears to be naturally fractured and whose prehistoric human origin and use is unclear or disputed.
From Greek 'eos' (dawn, early) + 'lithos' (stone). The term was coined in the late 19th century by archaeologists to describe stones from the earliest stone age that seemed too crude to definitively prove human craftsmanship.
Eoliths sparked a huge scientific debate because they're so rudimentary that nobody could prove humans actually made them rather than natural forces—it's like trying to find your earliest ancestor's fingerprints!
