For centuries, mainstream archaeologists have dismissed the idea that an advanced civilization existed long before modern times.

Now, an independent researcher claims he has uncovered ‘paradigm-shifting evidence of a lost civilization’ that hid a sophisticated code through geometry, symbolism, and monument design across the globe to preserve its knowledge ahead of catastrophic events.

Matthew LaCroix told Daily Mail the discovery, sparked by a recent find in Egypt, links symbols across continents and dates back 38,000 to 40,000 years.

According to LaCroix, this civilization tracked cosmic cycles, anticipated global disasters, and embedded teachings about human origins, the structure of the universe, and divine existence into monuments and sacred sites.

His investigation began after identifying recurring giant T-shapes, three-level indents, and step pyramids carved into ancient stones worldwide.

‘These specific symbols that are built in different size proportions, and the symbols are found in ancient stones around the world, are not supposed to exist; no cultures are supposed to have any cross-platform,’ LaCroix explained.

The symbols appear in locations ranging from Turkey’s Van region to South America and Cambodia.

According to LaCroix, the origin of this global system lies in eastern Turkey’s Lake Van region at a site known as Ionis.

He described it as the earliest source of the civilization’s symbols, architecture, and teachings, dating it to around 40,000 years old. He argues it preserves the original blueprint later carried to places such as Giza and Tiwanaku.

Recurring motifs, giant T-shapes, step pyramids, inverted pyramids, lions, and sacred geometry, appear at Ionis in their most concentrated form before repeating at distant sites worldwide, LaCroix added.

Nearby, the site of Kefkalesi provides one of the clearest examples of these symbols in stone.

The four-foot-by-four-foot basalt carving, known as the Kefkalesi relief, contains complex iconography that mirrors the symbols found at Ionis, Giza, and South American sites.

‘This relief became one of the most important artifacts for my research,’ LaCroix explained. ‘It connects Egypt back to this region and lets us back-engineer the global pattern.’

He pointed out repeating motifs: ‘Here are the T-shapes, repeating over and over. Here’s your step pyramid with three doors and the lion right here. These same elements appear repeatedly across sites worldwide.’

Regarding the lion, he added, ‘The lion is a guardian, and its placement helps explain the structure of the code.’

LaCroix said the relief solidified his interpretation of the symbols and accelerated his analysis of similar structures at the Sphinx Temple in Egypt.

Mainstream archaeologists, however, date known Lake Van sites to the Urartian period thousands of years ago and say there is no evidence supporting a pre-Ice Age global civilization, and no peer-reviewed research currently supports LaCroix’s proposed dating.
