Question

How can you know what happened millions of years ago if no one was there to see it?

Evidence and observation are the building blocks of all scientific inquiry; evolutionary science is no different. Evidence in the form of the fossil record, geological formations, and genetics attest to change having taken place and give clues to how evolution works. The theory of evolution puts these clues together into a cohesive explanation of the diversity of living things. Like all theories, the theory of evolution relies on tangible evidence as well as inference for those things that can't be observed directly. It is important to remember that Earth itself contains evidence of life in the past, and that this evidence provides critical support for the theory of evolution.​
