SciencePrehistoric (c. 12,800 years ago, Younger Dryas period)Abu Hureyra, Syriahigh confidence

Researchers found melt glass splashed onto small pieces of bone beside a hearth at Abu Hureyra, indicating molten glass fell into the village while it was inhabited.

Notes on verification

Confirmed by peer-reviewed publication (Moore et al. 2020, Scientific Reports) and corroborated by multiple independent science journalism outlets and direct quotes from study authors and lead excavator. The specific factual claim about meltglass on bone near a hearth is well-supported, though it sits within the broader, scientifically contested Younger Dryas Impact Hypothesis.
