We get oxgen from our mother via the umbilcal cord. The foetus does not breath through liquid.
If we had a way of adding oxgen to our blood we could live underwater.

Because when you breath you take air into your lungs, when an unborn baby 'breathes' it does so by absorbing oxygen through the umbilical cord of it's mother. It doesn't use it's lungs until after it is born.

We are not in water.
We are in an aqueous fluid. And it's because our lungs aren't working yet. Our blood is being oxygenated by our mothers through our umbilical cord.

if we are born into a pool of water we are still 'breathing through the umbilicus but when we are in the air this changes so that the blood goes to the lungs
