aaahhh yes....it's so nice to know that back along time ago, NOBODY made anything up, all art and written stories depicted on walls, cliffs, caves, rocks, tablets, etc.....were true representatives of actual animals, actual events, and human like beings.....there were no story tellers, no wanderers who would tell a fantastical story for a meal or shelter.....because like now, NOBODY back then, made anything up for personal gain........and people wonder why trump got elected......
know that you guys have this big narrative about what you think I am, what you think I believe, and what biases you think I hold.... And you're wrong!
While I disagree with you extremely vehemently on the c14

Just assuming that they're ALL FICTION and just somehow all the people had remarkably consistent descriptions even though some of them definitely didn't have contact with each other... That's truly insane!

Actually, its not that either.
Pareidolia is the psychological phenomenon of perceiving significance in vague or random stim-uli, e.g., seeing animals in clouds or the face of a religious figure in a food item. The results of this investigation indicate that the dinosaurs of Kachina Bridge are examples of this phenomenon and exist only as pareidolic illusions.

So carbon dating can only date the last 50k years.
Can someone eplain how they say mountain ranges are 200 million years old?
Therefore, by examining the ratio of carbon-14 atoms to carbon-12 atoms, scientists could determine the age of organisms' remains up to about 70,000 years. In 1960, this feat, called radiocarbon dating, earned its discoverer, American chemist William Frank Libby, the Nobel Prize for Chemistry.
Scientists then applied this dating technique to inorganic materials like rocks. They were able to measure the decay of various isotopes like uranium- 238 and thorium-232 in rocks to determine their absolute ages. The half-life of uranium-238, for example, is 4.5 billion years. Based on this science, we have been able to date rocks tens and hundreds of million years old and have determined that the Earth itself is some 4.6 billion years old.
This might help a little...

Now, perhaps you can explain how they know the exact amounts of the initial isotopes in the samples? How do they know what happened to said samples, in way of cross-contamination, over the years? Simple fact is, no one can know.

Well when you do 1000s/10,000s of samplings and the vast majority fit a pretty good pattern I think you can suggest they are in the ball park.

What pattern? They can't know the age without testing, and they cannot show what has happened to the sample over time. That's the problem with such dating methods. The world is not a closed system.

A real mystery.
