Answer my science question

This may well be two advanced for an answer I'll understand, but I am curious if anyone knows.
Question is.. What proof/math is there that a black hole is destructive. The physics says it forms a singularity where all matter that enters is destroyed. (or there abouts)
However I cannot understand or find any information on why this is the case.
Why for instance is it not logical to assume instead that a black sphere is formed, which still has mass and shape but light cannot escape due to the extreme mavity.
How can a blackhole grow if matter is destroyed, or is the word "hole" to ambiguous?

Anyone?

Then hole is a relatively poor choice for words of which something that becomes super massive would end up being a large sphere shape. Hence my confusion on why they're not call black stars or black planets etc.
Or is the matter shrunk so massively that it never grows to bigger than the size of the atoms it once contained.

See I understand what everyone is saying, i understand the science of event horizons, accretion discs etc. What I was curious to know is why scientist make the leap from the matter/particles being clumped together through extreme mavity to what is seemingly the common conception of a tear in space. Is there a theoretical reason behind that or is it just meer speculation. If the math breaks down inside a black hole why assume something that seems illogical and unrelated to what we normally observe in reality.
What seems more logical to me is that the huge amount of mass is ripped apart and crushed into something so dense, without the large distances between nucleus and particles that even after consuming thousands of stars it would still only be the size of a pea. However it would still have shape and size. You just would never be able to see it.

On what basis would a rotating black hole not have a perfectly spherical event horizon? The singularity at its centre is a point with no size, so that can't be any other shape. Meaning the event horizon should be uniform? Can something with zero size rotate in the first place - can a singularity rotate?

How can a singularity merg with another blackhole. Since it's infinitely dense, how does it even move. Surely by definition it would not have anything strong enough to actually cause it to orbit that object and how would two infinitely dense things attract each other unless they weren't infinitely dense.
