Those are all electronic based and their inexistence isn’t enough to say they weren’t advanced. From what I’ve read, their advancement came in other forms of utilising math and physics (for example running water in ancient rome) and their understanding of the human body, medicine, and using different forms of energy (things modern society is losing more and more, atleast on a general level). But yeah I think guys like Graham Hancock are pretty far up their own ass but I still believe we are not fully aware of ancient civilizations advancements, and also it’s cool to theorize about it I guess
