Carbon dating non organic
Carbon dating has a certain margin of error, usually depending on the age and material of the sample used.
A favorite tactic of Young-Earthers involves citing studies which show trace amounts of CCarbon dating, like other radiometric dating methods, requires certain assumptions that cannot be scientifically proved.
Ironically, given how supposedly useless carbon dating is claimed to be, Creation Ministries International rests part of their "101 Evidences" on carbon dating being a useful method for within several thousand years.
This of course contradicts claims that the Great Flood messed up how carbon was deposited, destroying their own argument.
Less astute creationists often conflate carbon dating with other forms of radiometric dating, attempting to "disprove" the true age of dinosaur fossils by "refuting" carbon dating.
This is meaningless - paleontologists do not use carbon dating to assess dinosaur fossils; dinosaurs became extinct 66 million years ago, more than a thousand times farther back than carbon dating can be used.
