Ghost, where is the proof?

Question

The idea of ghost have been around for a very long time. Why hasn't someone come up with enough evidence to stomp out the general logic?

Answer 1

Ha ha ha--that's kind of funny actually.

It is hard to find evidence that something does NOT exist, wherein strange phenomenon can be used as proof that ghosts do exist.

Answer 2

As more discoveries are made at the quantum level, your proof will be available.
