>Our skins are DRY. We breather AIR. There is no intersection between 99.9% of Human living and living UNDERWATER.

We came from the sea. Our blood and every other bodily fluid is saline. The exact same salinity of ocean water. Our bodies are buoyant, we have subcutaneous fat instead of fat marbled into the muscles, we have an instinctive ability to hold our breath and swim, traits we conspicuously share only with cetaceans.

It is not such a stretch that we would feel at home in the sea.

>Humans don't live UNDERGROUND either.

Actually, many do. Several northern cities like Toronto and Montreal are 50% or more underground, due to the low cost of expanding downward versus building skyscrapers and the low cost of heating/cooling a naturally insulated and thermally stable space. An entire city in Australia is underground due to the intense surface heat, with only a single surface building for visitors. The underground is another major frontier that we will expand into as a refuge from the effects of climate change.

You don't seem to know a whole lot about anything you've discussed so far but you persist in behaving as if you do. Allow for the possibility that your worldview is incomplete, and be receptive to filling those gaps with information from others who have devoted more time to studying topics you're unfamiliar with.

Something like this doesn't seem like it would be so bad. We could still go outside too, just not for long periods and probably with some kind of life support gear.
