Claim: Did humans and dinosaurs live at the same time?

The claim that humans and dinosaurs lived at the same time is false. Mainstream scientific sources, including Britannica and USGS, confirm that non-avian dinosaurs went extinct approximately 66 million years before the first humans appeared. Alternative sources, often based on biblical interpretations, dispute this by asserting that humans and dinosaurs coexisted, but these claims lack scientific support and are considered pseudoscience. Thus, the overwhelming consensus among credible scientists is that humans and non-avian dinosaurs did not coexist. The models diverge sharply — treat this as higher-uncertainty. Perplexity comes in highest (100%), while OpenAI is lowest (10%). OpenAI expresses higher confidence than Gemini on this claim. While some alternative sources argue for the coexistence of humans and dinosaurs based on biblical accounts, these claims do not alter the overall verdict. The scientific community overwhelmingly supports the timeline established by fossil records and geological evidence, which clearly indicates a significant gap of millions of years between the extinction of non-avian dinosaurs and the emergence of humans. The lack of credible evidence for coexistence reinforces the conclusion that the claim is false.
