Creationist claims carbon dating dating a medical student fox news
The carbon-14 dating limit lies around 58,000 to 62,000 years.Note that this limit of accuracy (which only applies to radiocarbon dating of all the radiometric dating methods) is still ten times longer than the time span required to comprehensively debunk young earth creationism.We can use it to get a range of dates, and use other methods to narrow or verify that range, but any information gleaned will be riddled with words like "approximately" and "estimated".This uncertainty is enough for a dedicated creationist to dismiss the entire science as quackery that's being made up on the spot.Creationists keep saying things like this, "How about the massive global carbon and coal deposits which render carbon dating inaccurate?
They lie, twist and misrepresent the facts about radiometric dating (and wholly ignore the many other corroborating methods) that tell us the actual age of organic materials to preserve their foundational fantasy at all costs.
All radioactive substances have these half-lives, and we know them to a pretty good precision.
Obviously once you get very little of a substance (after about ~10 half lives, IIRC) it's not very useful for dating materials, but as I said, there are a lot of them and their useful periods overlap, so we have a lot of ways to check our numbers.
The most fun and frustrating people to talk to are creationists — “Young Earth Creationists” to be more precise.
These are the people (around 50% of Americans) who think that the Earth is only about 6,000 years old because the bible says so.
But to answer WHY they do it, it's because they have to.
