History is always intriguing for the curious minds, as everything we know, have known, and will know is just incomplete pieces of the entire picture of humanity's past.
Recent discoveries seem to indicate the possibility of ancient civilizations referring to planet Earth as 'home' much earlier than previously thought. Why mainstream researchers choose to 'overlook' details and clues pointing to the existence of much older civilizations remains a puzzle for many.

Evidence of civilizations inhabiting our planet before recorded history can be found everywhere around the world. In ancient Egypt, Mesoamerica, and Sumer, we find written texts about great civilizations in the distant past, great rulers, and millennia-long 'golden ages.'
One of the most striking examples of '100,000-year-old civilizations' can be found in Africa. This remarkable discovery actually took place at a site in South Africa, about 150 km west of Maputo port. There, archaeologists discovered the remnants of an ancient metropolis, according to surveys, it covers an area of about 1,500 square kilometers (almost equivalent to the area of Hải Phòng).

According to researchers, this ancient city was just part of a larger, even more mysterious community with a scale of about 10,000 square kilometers and is believed to have been built from 160,000 to 200,000 years before the Common Era. The geology of the surrounding area is also quite unusual due to several gold mines located nearby.
Researchers have proposed that these remnants may stem from an ancient Anunnaki civilization, vanished in the distant past, who inhabited and settled in this area for gold mining purposes.

In the Amazon region, other civilizations have been discovered, possibly predating even the Inca civilization, perhaps their ancestors. No one could have imagined that somewhere in the remote wilderness of the Amazon lies a lost civilization.

Approximately 450 geoglyphs, primarily featuring simple geometric shapes - squares, circles, or polygons - have been unearthed so far across an area of 13,000 square kilometers.
Rapid deforestation coupled with Google Earth has enabled the discovery of hundreds of geoglyphs (giant ground drawings) in 200 different locations, within a 250 km by 10 km swath in the Amazon. Similar to the Nazca lines, these mysterious geometric designs in the Amazon can only be truly seen and assessed from above.
Many remaining parts are clearly part of an ancient civilization previously unknown, emerging now beneath the Amazon rainforest canopy. According to researchers' speculation, these peculiar shapes could be ancient irrigation channels and livestock enclosures.
However, for some reason, no excavations have been conducted in the area to date, and all connections with indigenous tribes in the Americas regarding this archaeological site are mere conjecture. We still know nothing about the creators of these mysterious geoglyphs.
Furthermore, an expedition conducted near the border between Bolivia and Brazil unveiled mysterious pyramids in the Amazon: Traces of an ancient civilization. Some researchers speculate that these pyramids could have a natural pyramid-like shape, but many others firmly believe they are architectural structures built in the distant past by a previously unseen civilization.

However, a notable fact is that the mysterious pyramid structures were first identified through NASA's satellite image C-S11-32W071-03, published in 1976: they demonstrate the presence of pyramid structures within pristine forest areas. The Machiguenga people named their sacred area Paratoari. Is this a product of nature or human endeavor? Is it merely a sacred ritual site or the lost city of the Incas?
These images have spurred numerous investigators to venture into the Manu region, a dense tropical rainforest in southeastern Peru, hoping to determine whether these architectural structures were indeed constructed by an ancient civilization, lost to time.
While some cutting-edge researchers still refute the hypothesis that these pyramids were built by humans, others posit that the symmetrical spaces between the pyramids and their uniform shapes suggest they are not natural formations.
Similar to the Paratoari pyramids, the recent debate over the Visoko pyramids in Bosnia presents two opposing views: one argues they were built by humans, while the other contends that the structures formed naturally.
Nevertheless, a fundamental truth persists: within the dense and sprawling forests of the Amazon, countless mysteries exist that could shed light on how ancient civilizations thrived in the distant past.
