Hmm, with how drastically you changed humans for this hypothetical, its not really above how humans would have adapted to make underwater cities, instead of giving humans gills and stuff, maybe making them more similar to existing marine mammalian species would have been more engaging. How aquatic humans that still need air to breathe would develop cities would probably interest more people imo, the changes needed to give humans gills means they arent even really close to human anymore. Gills are terribly inefficient at intaking oxygen, this prohibits large brains which take an astronomical amount of oxygen to run, as does our whole body, with the amount of changes that would be needed to allow humans to supply their body with enough oxygen via gills, they wouldnt even resemble humans anymore, dolphins look more human then that would.

Without fire, we would never get past the stone age.

I think within such an alternate world. The alternate human species would still likely follow much of the same rules as current oceanic life.

Oceans are deserts. Oceanic life is concentrated in locations where sunlight is able to reach the seabed. Additionally. Oceanic regions that are located near the runoff of major continental rivers usually have much more biodiversity due to increased minerals and resources available within the water, beyond just sunlight. Early cities would still be coastal around these river hotspots where agriculture is most Feasible.

Eventually such a society would likely find efficient means of farming via floating platforms. But the primary energy producer would still be the sun. The depths would still be a massive expanse of desert. And we wouldn't have that many reasons to quickly evolve the ability to explore the deep depths. The challenge of exploring trenches would likely be greater then that of exploring some of our tallest mountain peaks. Sure. You could dive in a high pressure submarine to protect your body. But you wouldn't be able to nonchalant have a society living down in these trenches. Even if their bodies could sustain the pressure. They'd be living off artificial light and extremely limited resources.

That said. They'd still be able to create thriving societies within the more habitable regions. And migration between regions would still remain feasible.

I would suggest repeat less information and go more in depth to how humans good look provide drawings and stuff do like the concept tho

Big problem, building anything underwater is a pain in the ass. Fire no, electricity no. Hybrid life maybe, merfolk not yet.

"we would be underwater" repeated a hundred of times.
