The real reason why the earth is not flat is not because it isn't, necessarily. The reason is this.

Round earth physics has a rather complete physics to it. Flat earth physics does not.

Round earth physics may have some flaws in it. All they are is flaws. But flat earthers try to use the flaws to say that the earth is flat, when all the flaws do is suggest that round earth need some additional explanation.

In other words, flat earth theory is not even theory, technically, because round earth is not theory. Round earth is fact, even though it has a few mistakes in the understandings about it.

1) What properties do you believe space has that would necessarily suck away Earth's atmosphere?  What is the basis for your assumption?  To make such an assumption, you must have a theory or model of how and why this would work.

2) With regards to the Earth and its oceans and the moon, first you need to know what gravity is.  According to general relativity, objects with mass create curvatures in space.  The effects this curvature has on other nearby objects is what we call gravitational force.  We know that space curves as a result of mass because this was confirmed by astronomers testing Einstein's theory.  Initially, this was confirmed when astronomers were able to observe distant stars that should have been blocked by the Sun but were visible because their light bent around the Sun due to the curvature in space as a result of its mass.  

So, because the Moon and Earth are also mass objects like the Sun, they also create curvature in space.  The gravitational forces created by each body affect the other, but because Earth is something like 80 times more massive than the Moon, its gravitational pull is much greater.  This doesn't mean the Moon's pull is negated; it still exists, and we see its effects on our oceans (i.e. The tides).  

The moon doesn't crash into Earth because it's in orbit.  If you imagine throwing a rock horizontally, the rock falls to Earth due to gravity.  If you were to throw a rock really, really far (say, a few kilometers) it would fall to Earth too, but to hit the ground it would need to fall farther to account for Earth's curvature, and so it would.  Now, if you threw a rock really, really, REALLY far, it's possible that you could throw it so hard that it would keep falling and falling but never hit the ground, and instead it would circle the Earth as it continually falls around Earth's curvature.  This is what happens with the moon; it's continually falling towards Earth but never hits it because it is at the right speed and distance from Earth that it stays in orbit.  And so 'round and 'round it goes.
