Three main creationist claims that deny the scientific nature of evolutionary theory are refuted: that it is not falsifiable, predictive, or observable. It demonstrates that evolution is falsifiable since improbable findings could challenge it, and discrepancies in data drive further research. The evolutionary theory is also predictive and retrodictive, as evidenced by Darwin's confirmed predictions about pollinators and the discovery of marsupial fossils in Antarctica. Moreover, evolution is observable and testable, with numerous documented cases of adaptation and natural selection. In conclusion, evolution meets scientific criteria and has been consistently validated, thus refuting creationist assertions.
