Spacetime is a theory of what gravity is and why it exists in the first place. Light doesn't have matter, gravity doesn't attract something unless it has matter. So why does a black hole suck in light? Gravity doesn't exist, his theory of relativity is a theory that the more massive an object is the more it bends spacetime and attracts everything, not just matter.
[Edit]
And he didn't prove it, nothing can be proven right.
Spacetime is the medium that gravitational mass warps. Light does have momentum though, so why not consider it as matter. Gravity bends light, look up gravitational lensing of light. Black holes do suck in light, and the phenomenon gravity does exist, although it can be explained in different ways, hence the theory. You have little understanding of physics, and poor reasoning is no excuse for a false conclusion.
As for the reply to your edit, you might as well just give up on trying to learn anything because nothing can be proven right,id est by using your reasoning.
