What if humans couldn't swim?

What if humans couldn't swim?

They would sink.

Yeah but how different would the history and technological advancements of humanity look?

It's a legit question.

First can you describe the physics of a world where humans cant swim?

It's the exact same except people can't swim.

Why not? What prevents swimming? Is it not physical but neurological? Do we just stop moving when submerged? You have to explain why first.

Fewer people would have drowned, since they would avoid ever getting in water.

Maybe in this world all people are black

Couldn't most people including sailors not swim for most of history and actually most people still can't?
It'd be like real life.

only white people can swim

Our motor skills disappear once 50% of our body is under a liquid, because it is the will of the demiurge.

fishing would be radical as fuck

Didn't they invent float jacket or something?

Not much would change because most people don't swim very often anyway. Same goes for in the past.

Niggers can't swin.

idk ask 13% of the pop of the usa i guess

OP said humans

I guess that settle down the question: are niggers humans?

We would all play basket ball

seafood would be less predominant in maritime cultures because stuff like spearfishing cant arise pre-SCUBA if we can't swim

naval tech and exploration would probably also be less advanced for fear of falling overboard

WRONG, dumb ass! Humans float naturally.

you mean witches?

Floating like humans float.

tbf humans cannot naturally swim unless they are taught how to.
