A large part of cave paintings… are not what they seem.
They are not ancient proto-art, hunting stories poorly drawn on the walls and ceilings of caves.
It’s encrypted data <— Left there by members of an advanced interstellar civilization.
But with their race members… chased… in desperation hidden in the caverns.
Trying to leave a trace that they existed, that they were there.
They painted them with full knowledge of chemistry, of the duration of paints and pigments.
For someone else to find them in the future and have the mind and knowledge to see past just people in loincloths, chasing animals with a spear.
After so many years, the painting is no longer as harmless as the cave paintings. Researches have shown that lead contains paints of various, including well-known, manufacturers. So only in 5 out of 21 prototypes the level of lead did not exceed the maximum recommended indicator of 0.009%. A new law requires the RRP Lead Renovator Initial Course is mandatory and must be passed by the end of the year https://www.ablesafety.com/course/8-hour-epa-rrp-lead-safe-certified-renovator-initial-blended
