My name is Matthew LaCroix and I am an author and ancient history expert who has extensively studied the secrets of lost civilizations, megaliths, earth cycles and ancient texts for two decades.
This journey of uncovering the secrets from these mysterious lost civilizations would eventually lead me to eastern Türkiye in early 2023, where I found evidence of a previously unknown civilization that showed signs of being highly sophisticated in megalithic building, as well as culturally and spiritually advanced.
However I can't do this important task alone, so over the course of the last ten months I have been putting together a team of experts to take part in a revolutionary documentary and expedition to uncover the secrets of this lost civilization and finally tell its forgotten story to the world.
