it's worse than that- I was being generous giving huge leway- radio carbon dating goes wonky after much less than 50,000 due to condiotions that are less than ideal- Which evo's fail to account for or even concider
False. Radiocarbon depends on the half-life of C-14; by the time you get to 50,000 years, the signal to noise ratio makes normal techniques inadequate. (There are a few labs experimenting with better methods which may permit analysis of older samples, but those are not commonly used.)
Archaeologists know this, and take it into account. "Evos" don't often use radiocarbon dating. They use other forms of radiometric dating that are suitable for older specimens and specimens that contain no carbon.
