Many ancient artifacts simply baffle people and make them believe that our civilization on Earth is not the first and only one.
There are many indications of such anomalies
For example, in the Arctic region of Canada, a fossilized human finger was found, the age of which is estimated at 100 - 110 million years.
Not far from the Utah Delta, in a shale rock 300-600 million years old, they found the imprint of a human foot, shod with a sandal.
Or else - metal spheres that have been encountered by miners in South Africa over the past few decades.

The origin of these spheres, which are usually 2-3 centimeters in diameter, is unknown. The most amazing thing is that the rock in which they are found belongs to the Precambrian period, its age is 2.8 billion years.
Or here - absolutely real giant stone balls in the jungle of Costa Rica
Workers clearing the Costa Rican jungle for banana plantations in 1930 stumbled upon dozens of stone balls, many of which were perfectly spherical. They varied greatly in size (from the size of a tennis ball to a huge ball 2.5 meters in diameter and weighing 16 tons). Although the stone balls are clearly man-made, it is not known who made them, for what purpose, and how they managed to achieve such precision.
Or, right in the Russian Arctic - the mysterious spherulites of Champa Island
Champa Island is one of the remote and virtually unexplored islands of the arctic archipelago Franz Josef Land, Russia. The territory of this island is small (only 375 sq. Km), but it attracts researchers with the riddle of its stone balls of impressive size and perfectly round shape - where did they come from on these uninhabited lands?
Fortunately for all lovers of the unknown, there are more than enough strange and wonderful phenomena in the world. And unambiguous answers to the questions - where is it all from and why - still do not exist.
