The ridiculous narrative is that it was constructed by the Hittites of [sic] Phyrgians around 3000 BC
And was rediscovered in 1963 by an anonymous local who kept losing his chickens
Leaving out that they were expanded into their modern form during the early middle ages and were continued to be used until the Greeks were expelled from Turkey in 1923…
Chickens is a code word for kids being smuggled by pedophilia rings
And underground tunnels are used for this purpose
Even if there are tunnels dug for the express purpose of paedophilic trafficking, surely, that’s not the ONLY reason people build them?
Also, the idea of omnipresent dedicated tunnel networks for child smuggling strikes me as extreme overthinking and a stark example of how these fanciful hysterias actually get in the way of actually fighting organised child exploitation through spreading gross misconceptions.
Humans could not build elaborate tunnels without light
The light bulb was supposed to be discovered in 1879
And torches or candles would not have sufficient oxygen to keep burning
[citation needed]. Especially considering you yourself mentioned the impressive ventilation vents. Also, since we are talking about the Mediterranean, what about oil lamps?
Humans require sunlight
Our bodies have photoreceptors that respond to sunlight and convert it to energy
Survival without sunlight would be limited to weeks or maybe months
This is a flat-out lie. There are plenty of cases of people have been imprisoned for years, even decades, without ever seeing the sun. Living without natural light takes a heavy toll, yes, but humans are not obligately photosynthetic, or indeed photosynthetic at all!
Also, this is missing the point of these cities (at the very least by their Byzantine form): They were unassailable refuges, since Cappadocia was a main raid and invasion route for eastern forces into Anatolia, their use continuing into the Ottoman era as the Greek Christians sought shelter from persecution. When things were peaceful, light is a non-issue because you can go, and indeed spent much of the day, OUTSIDE (…looking at the patterns among the Tartarianists, perhaps I should not take it for granted that they are aware of this concept…), but when the hordes come in, the inconveniences are well worth it against what invaders - or even worse, slave raiders - may do to you…
The underground complexes had doors of massive rolling boulders, to be closed from the inside. Perfect for just sealing yourself SHUT and endure until the invaders have passed on. What use would such doors have for paedophile rings?
But if that’s (somehow) too boring and mundane for your stupid tastes, fine. Let’s say they were self-sufficient nuclear bunkers, like the Vaults from Fallout (predictive programming - they even knew about Trump annexing Canada! And yes, ghouls are completely scientifically accurate), in which people sought shelter against all the Ancient Alien nukes. At least this still makes more sense than what you propose.
