Well it depends on what you're describing, if you mean infinite as a math concept, then you don't need to prove it, in the same way you don't need to prove a "1" is actually a "1", you just say it's a "1" and use it in a problem.
If you mean infinite in our physical reality, like space being "infinite," the laws of physics don't allow that.
