25,000-year-old underground pyramid discovered, not built by man
The pyramid may have evolved organically as a result of geological processes.
Water and erosion may have sculpted the pyramid form over time.
But the exact angles and symmetry of the structure are not explained by this theory.
An additional theory is that the pyramid was constructed by an unidentified, long-extinct culture.
This notion is corroborated by the pyramid's location in a secluded and uncharted region.
But there isn't any hard data to back up this assertion.
Another possibility is that aliens constructed the pyramid.
Although there is criticism towards this notion, it is worthwhile to take into account given the size of the universe and the potential for extraterrestrial life.
In the end, the pyramid's history and function are still unknown.
To fully explore and explain this intriguing finding, more investigation is required.
