Meteroites carbon dating
These findings give researchers insight into the chemical processes taking place on Mars and will help aid future quests for evidence of ancient or modern Martian life."There are many kinds of organic carbon in Martian meteorites that aren't from life forms," said study co-author A. Timothy Jull, a UA professor of geosciences whose lab analyzed carbon from some of the meteorites described in the new study.The analysis by the UA Arizona Accelerator Mass Spectrometry Laboratory showed that some of the carbon on the meteorites originated in Mars and some of the carbon came from terrestrial contamination."If there was life on Mars, there's carbon on Mars available that life could use," said Jull, who is the director of the lab.Desmond Clark (1979) wrote that were it not for radiocarbon dating, "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation" (Clark, 1979:7).Writing of the European Upper Palaeolithic, Movius (1960) concluded that "time alone is the lens that can throw it into focus".Hypotheses about the source of the molecules include contamination from Earth or other meteorites, ancient Martian biological life or the results of chemical reactions on Mars.The new research provides strong evidence that some of the carbon-containing molecules did originate on Mars, but not from ancient life.

Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.
