Nothing because Earth is not a globe; rotating or otherwise.
No, Earth is a globe, which is rotating.
If you wish to assert it isn't and expect anyone to take you seriously, you will need vastly more than your pathetic baseless claim.
Earth has been proven to be a globe beyond any sane doubt.
It has been proven to be rotating beyond any sane doubt.
Why would the water fall off Earth if it was a ball? (Happy, phrased in a way that you can answer it without admitting reality).
You are yet to substantiate that in any way.
And there is no reality of a pull, it's all push on push.
Pulling on a rope proves that to be nonsense.
It is also completely unrelated to the topic.
So, to answer your question by using a ball and water on it, the atmosphere squeezes, pushes that water down against resistance to that water by atmosphere below, except the above atmosphere, plus the water is too great and so it falls to the ground.
So Earth would have water be pushed by the atmosphere to the ground?
The complete opposite of what you were saying. That means it would stick to Earth, not fall off.
As for your denpressure BS thrown in, that is still just unsubstantiated BS.
The pressure below is greater than the pressure above which should push the water upwards.
There is absolutely no reason for air to push water downwards.
So if you want to assert that the air magically pushes the water down you will need to back that up as well.
And before you assert that is wrong, you need gravity acting on the air to sustain that pressure gradient. That gravity would hold the water to Earth.
So no reason for the water to fly off Earth, spinning or otherwise.
In fake space with the fake vacuum in your adhered to universe, you have a ball that spins and water doesn't fall off because of a fictional unknown made up force.
The only one appealing to fake space here is you.
We have real space, with real forces, which you reject because it doesn't fit into your fantasy world.
And yet people actually go along with this stuff. It absolutely beggars belief as an adult but is understandable for a child to fall for the nonsense.
Yes, because they realise your claims are BS.
Again, Earth isn't a tiny ball being held up above a much larger ball.
As such, your comparison to holding a ball is complete garbage.
Sane people realise this. Why can't you?
