Welcome to the forum
Could you explain what water you are asking about?

PS I’ve split your post from the pictures section because it didn’t seem relevant to that area.

This question about why space doesn't suck away Earth's atmosphere (https://www.thenakedscientists.com/articles/questions/why-doesnt-space-suck-away-our-atmosphere) addresses a similar concept and will, I'm sure, prove useful for you.

"Falling" means approaching the ground, so you can't logically fall into space.  The fact that objects fall to the ground everywhere on the planet is probably the simplest proof that the earth is spherically symmetric.

Why stuff falls to the ground is gravity. Fascinating force, precisely calculable and applies everywhere in the universe, but we have no idea how it works.

Because space is "up" from where the water is.
