I feel kinda contrary to this.... I admit that some stuff they have come up with could be true and are. I think their are some good points "young earth creationists" have come up with
They have, on occasion, come up with some good points -- unfortunately none of them disprove evolution let alone prove their Young Earth Creation hypothesis. And the latter is what they need to do, prove -- using the tools of science -- that their Young Earth Creation hypothesis fits the observed facts better than evolution does. They have not come close and probably never will as their hypothesis is designed to fit one literal interpretation of the first few chapters of Genesis and neither their hypothesis nor that particular literal interpretation of the first few chapters of Genesis is a good fit for the observed facts.
