Why do people think that rubber sheet with a ball analogy for gravity is good?

I don't know the reason.
A lot of really clever people have used it, but I think it's more or less useless.
I used to like it, before I really thought about it.
The idea is that the ball distorts the rubber sheet just like mass distorts space.
The distortion of space (spacetime to be exact) is the basis of our modern understanding of gravity.
Some people like this analogy until you point out the problems.
Some things are just really hard to explain.
It was simpler with Isaac newton. He just had no explanation for gravity.
OK, it's only an analogy, but here's one problem:
The rubber sheet is only 2 dimensional, of course.
Here's another problem : The whole analogy is meant to "explain" gravity.
What causes the ball (mass) to distort the sheet (space)?
The ball is pulled towards the Earth by.........gravity.
Yes, but no , well, I mean........

Where does gravity stop?
The earths gravity extends across the whole universe but it gets weaker and weaker very quickly as you move away from the earth. It's a bit like a ball on a rubber sheet distorting the sheet around it a lot but not distorting the sheet a lot further away.
