Ancient Nanostructures: Aliens or Lost Civilizations?

A prehistoric object discovered in a rare or unlikely environment is known as an artifact out of place (oopart). Ooparts are artifacts produced with technology too advanced for the level of society associated with the period in which they were discovered.
Many people see ooparts as proof that popular science intentionally or unintentionally ignores important areas of information.
In 1991, geologists conducting geological surveys along the banks of many Russian rivers found hundreds of tiny spiral-shaped objects, some as small as 1/10,000th of an inch in diameter.
The researchers were conducting mineralogical surveys in the Ural Mountains in preparation for the prospect, so you can imagine their surprise at the discovery.
They were discovered at depths ranging from 10 to 40 feet (3-12 meters) and are estimated to be between 20,000 and 318,000 years old.
The largest are 1.18 inches (3 centimeters) long, while the smallest are only 2.5 microns long. The average strand of hair is around 100 microns long, for comparison. Copper is used for the larger coils, while tungsten or molybdenum are used for the smaller ones.
Their shape indicates that they are not natural metallic particles, but rather advanced nanotechnology components.
These ooparts have ignited a raging debate that is still going on today. The enigmatic microscopic structures are 300,000 years old, according to scientists. Is it possible that Earth had a technologically advanced civilization at the time, or are these objects evidence of another intelligence centered on our planet?
Due to several well-known limitations, our modern society has recently developed nanotechnology. For humans who lived 300 years ago, conventional science does not recognize a technical degree beyond the occasional use of fire.
Scientists have not been able to figure out who or what created these structures, but one thing is certain: they are not normal, as no established mechanism can create them.
While some have claimed that these tiny structures are simply debris from test rockets from the nearby Plesetsk space station, a study by the Moscow Institute determined that they are too old to be of recent manufacture.
Dr. EW Matvejeva of the Central Scientific Research Department of Geology and Exploitation of Precious Metals in Moscow writes in 1996 that the elements, although thousands of years old, are of technical origin.
Arguments that spiral-shaped artifacts are made and still very old have been supported by facilities in Helsinki and St. Petersburg.
Four separate facilities in Helsinki, Saint Petersburg and Moscow have investigated the objects. However, with the death of Dr. Johannes Fiebag, the lead investigator of the find, in 1999, further study of these tiny structures appears to have come to an end.
This discovery raises many concerns. Was it possible for humans to master nanotechnology during the Pleistocene epoch? Who could have learned such advanced industrial technology during the time of Homo erectus? Is this evidence of a long lost culture on Earth, or are these objects left behind by extraterrestrial visitors?
We can never find out.
