Well maybe we are more advanced than we know i dont know, there are many theories also based on ancient cultures that have existed. For example related to the creation of the pyramids, ancient writings, they all tell or at least share some sort of possible story or thing in the past that we cant confirm till today. Yall played Assasins creed? I never finished the game series, but as an example i believe in one they showed a glimps of adam and eve that actually lived in an advanced world or something, but i never saw the story completely but somehow its like humanity restarted or at least this is a theory that game holds. There are gonna always be deceiving things in this world, hard thing is to tell the difference from real or fake .
