How can Earth hold Atmosphere?

If you have a cup or glass and you pour water in it, the container can hold only some water and when the water level increases over edge of cup or glass, water will pour away.

Now imagine air instead of water and Earth instead of cup. All the armosphere should pour away from Earth, leaving Earth whisout atmosphere. So how can we breathe? Are there any invisible boarders around Earth preventing atmosphere from escaping?

Does it have to be invisible?
How do you define down?

Can you see it?
Against the acceleration of Earth.

Why cant you see it?

Down was to determine your udea or model of the universe.
Ill assume by your answer it is Universal acel and that gravity doesnt exist.

Your analogy makes no sense. What "water" is "pouring" into the "cup" of the earth?!

If you have a cup or glass and you pour water in it, the container can hold only some water and when the water level increases over edge of cup or glass, water will pour away.

Now imagine air instead of water and Earth instead of cup.
All the atmosphere should pour away from Earth,

why?

leaving Earth without atmosphere.

we are here sow it hasn't, it is gravity that holds the atmosphere to the surface of the earth.

So how can we breathe? Are there any invisible boarders around Earth preventing atmosphere from escaping?

No invisible borders are required, as down is toward the center of the earth, Earth being a globe, there are no edges for anything to fall from, let alone to wear?

If you have a cup or glass and you pour water in it, the container can hold only some water and when the water level increases over edge of cup or glass, water will pour away.

Now imagine air instead of water and Earth instead of cup. All the armosphere should pour away from Earth, leaving Earth whisout atmosphere. So how can we breathe? Are there any invisible boarders around Earth preventing atmosphere from escaping?

You bring up a good point. It seems unlikely that the atmosphere touches the boundary and vacuum of "space" , yet remains on Earth. There is probably a come over the Earth containing the atmosphere.

Vacuums don't suck. The vacuum of space does not suck the atmosphere away from Earth. So, there is no reason for the atmosphere to leave Earth as there is nothing pulling it away from Earth.

Aah
But he believes its invisible because he can see the night sky?
If earth is moving up, and using your cup analogy - there does not need to be a "lid" to hold the air within the walls.
So all thats needed are walls.
And walls dont need to be invisible.

You have atmosphere + you have Earth accelerating 9.81 m/(s*s). Either atmosphere accelerates with Earth (why then? for example water falls down - doesn't accelerate - as long as it is not in a cup-like object), there are some invisible bounds or atmosphere just leaves Earth.

Actually, yes. Atmosphere should not only escape down but also up thanks to vacuum.

It sticks to the Earth. Just like water. It's all attracted to the center of the Earth. There are no invisible bounds involved. Because Earth is so big, gravity is enough to keep atmosphere in place.

The atmosphere keeps getting thinner and thinner as you go up, to the point where there is no atmosphere to get even thinner. This is where you enter space.

Ahhh please elaborate how this ‘nothingness’ gets bend/warped/wrinkled/curved by the mass of large celestial bodies.
Either your ‘nothing’ premise is false , or it is something that can be bend and i like to know what part or properties of the ‘nothing’ is being bend because of  earth’s ( or any celestial body’s) mass.

Objects are under acceleration towards the earth of 9.8m/s². This includes the atmosphere. It's not going to leave due to the nothingness of space.

The armosphere may be limited to the outskirts of the infinite plane.

But, since this is the first use of the term armosphere , feel free to provide a definition.

Are there any invisible boarders around Earth preventing atmosphere from escaping?

Earths magnetic field is invisible and does prevent the atmosphere from escaping. If we had no magnetic field, not only would we all be roasted by the sun, but the atmosphere would be sheared away over time

This is why Mars, everyones favourite place to suicide, will never hold onto an atmosphere. Even if we made Mars a tropical oxygen rich environment.

Venus however would be a much more friendly place to colonise but I digress

So Earth holds onto an atmosphere with an invisible force called a magnetic field (among other reasons)

I wouldn’t say the magnetic field holds the atmosphere in place.

It protects the atmosphere from being stripped away by solar wind (I think), but that would be a process over millions to billions of years.

It has little to do with the claim that the atmosphere can’t exist next to a vacuum, which if true would be virtually instantaneous.

BTW. Venus looks incredibly inhospitable.

Iow...you don’t have a f’ing clue, sell it as a placebo reality based on mathematical musings and shun those who dare  to raise an eyebrow and throw the ‘ignorance’ card at them.

You confused person  ... you claim the vacuum is ’nothing’ while there is no such thing beyond the Kármán line that has the properties of ‘nothing’.
