claim: The ancient rock carvings show modern-day technologies like computers, Astronaut suits and bicycles, etc. which suggests that our ancestors are more technologically advanced than us
evidence: The carvings of the bicycle and astronaut are done recently after their inventions are made. The man sitting at a computer is not a carving, but an artwork made in 2006. Similarly, symbols in some other carvings have not yet been deciphered, and some of the associations with modern symbols like Wi-Fi, rockets and transformers, etc, could be due to visual similarities rather than actual representation as there is not enough evidence to support them. Hence the claim made in the post is MISLEADING.
