There are dozens of different isotopic and other dating methods, some of which, based on half life decay, are more accurate into the millions of years. A lot of ‘young earth’ sites like to blatantly confuse the reader by bringing up radiocarbon dating anytime radiometric dating is mentioned so they can say it isn’t accurate over 30K years (actually 60K but not the point here). Radiometric measurements can be accurate into the billions of years (in Uranium-Lead dating), Samarium-neodymium to about 20 million years, Potassium-argon at 1.3 billion years... etc.. and there are also

argon-argon (Ar-Ar)
iodine-xenon (I-Xe)
lanthanum-barium (La-Ba)
lead-lead (Pb-Pb)
lutetium-hafnium (Lu-Hf)
neon-neon (Ne-Ne)
rhenium-osmium (Re-Os)
uranium-lead-helium (U-Pb-He)
uranium-uranium (U-U)

Dating methods.

Don’t be deceived when some point out radiocarbon dating when talking about fossils. They are being purposefully deceptive.

Well done mnehring! Best description of radiometric isotopic dating I have seen at FR.

and we should believe this because “scientists” say so?

Think meteorologist. (weather man)

Think Photosynthesis.

Photosynthesis: Definition: Natural chemical-process by which chlorophyll (magnesium-containing pigment in green plants, blue-green algae, phytoplankton, and green and purple bacteria) uses sunlight (radiation) energy to convert (synthesize) water and atmospheric carbon dioxide into life sustaining organic compounds such as glucose. Being also responsible for almost all the oxygen in atmosphere, >>>>>photosynthesis is the basis of all life on earth.<<<<<<

OOOPS! >>>>> Until recently, all life on Earth was believed to be dependent on the sun. But in the last 30 years, several new deep-sea ecosystems have been discovered that utilize an alternative source of energy.
Instead of sunlight, vent life relies on hydrogen sulfide - more commonly known as rotten egg gas and toxic to most land-based life.

In a process called chemosynthesis, specialized bacteria create energy from the hydrogen sulfide present in the mineral-rich water pouring out of the vents. These bacteria form the bottom level of the food chain in these ecosystems, upon which all other vent animals are dependent.

Scientists are only right until they are wrong. Which is unfortunately for them, is all too often.
