The theory of evolution is also easily tested to a high degree of certainty.
It has successfully predicted fossil finds and their characteristics. It has also successfully predicted genetic homologies, that needn't exist if it wasn't for common descent
No. The fact of gravity is easily tested. The theory or theories of gravity try to explain why gravity does what it does. The same goes for evolution. That populations of organisms change over time is not in dispute. The Theory of Evolution, attempts to describe and explain why that change occurs.
