How can you know what happened millions of years ago if no one was there to see it?
Scientists use a variety of methods to understand events from millions of years ago, including fossil analysis, radiometric dating, and geological studies. Fossils provide clues about past life forms and ecosystems, while rock layers can reveal the age and sequence of events. Additionally, technologies like isotopic analysis help reconstruct ancient climates and environments. Together, these approaches allow researchers to piece together a comprehensive picture of Earth's history despite the lack of direct observation.
