If you're interested in ancient civilizations, you might also enjoy studying inexplicable examples of ancient technologies (kind of a controversial "fringe" topic, but downright addicting to research!). Maybe start by looking up videos by a man called Brien Foerster... and I'll also recommend a channel called Bright Insight (although the latter tends to repeat content in many videos... still worth a look, though). If you already know of these videos and/or are completely uninterested, forgive me :)
Thanks for the thought-provoking post!
