I have taken geology classes and it is well known that carbon dates for coal and such can only go back to 40,000 years as the half-life used is no older. The next marker is potassium-argon dating to 387,000,000 years and before so that leaves an incredibly large gap in which most life of larger fossils falls which cannot be reliably dated by any radiological method. (Uranium is 4.6 billion and solidified igneous rock can be dated to 4 billion years) As noted recently, the 'days' are 'periods of creation' which overlap so we can only hypothesize reality until Jehovah sees fit to give us a firm answer. MAN and his history is very reliably dated by Scripture so these caveman 'stories' are just lies laid uopn lies. The skull tells you if a bone is a human or primate by the placement of the brainstem and the opposable thumb on the phalanges. I told a guy recently that you cannot tell me my house is 4 billion years old because I made bricks out of stone. So 'relativistic dating' must be used which is incredibly hard because of so many factors with so many variables. (Layering, erosion rates, fault line shifts, etc.) empirical evidence is almost useless because you cannot derive an experiment that you can repeat to get the same reliable results. Ok, so I am starting to sound like the OJ criminal defense team, lol. I'll leave it at that...
