If all things are expanding away from a certain point they can never collide.
​
Of course they can, and they do. There can also be local motion relative to other local objects as well as objects developing over time.

It is an expansion. But as has been pointed out to you, the overall expansion of space has nothing to do with what happens on a local level.
​
The analogy to a ballon, like all analogies, presents an incomplete picture. There are also local events, and we see them. We can see new stars being formed, old stars dying, things colliding. The univese is dynamic and changing and old, very old.
