Some creationists claim that "Evolution has been scientifically proven false". How, exactly?

By pure logic and common sense (in my own opinion). I mean I have never believed that I evolved from an ape, or that whale hip bones evolved into barely there hip bones. I know darn well that this earth is not billions of years old because the sun would have already blown up and died. People would have killed the planet ten thousands times over already. There is no way that this messed up planet is billions and billions of years old. The cromagnon man and neanderthal mans bones were made up of a bunch of monkey bone and bigfoot bones and hey maybe even a human bone. Darwin floated in a boat and thought 2 plus 2 was 5. Animals and humans dont change much over a span of time. Dinosaurs weren't even around millions of years ago they were here like 4000 years ago and they died off due to man killing them off and climate changes and the flood. The Grand Canyon was made in a few weeks. Even the rock layers of the earths crust were formed in a few years not hundreds of thousands and billions of years.
