That's interesting, I didn't know that.

> If existence requires perception, what about that which is perceived yet does not exist

Great question! And may I assure you, there is no way to find out whether the object exists or not, without us conducting some experiments and perceiving the results of it. It's easy to demonstrate with a phantom limb. Yes, one feels a limb is there, but when he looks at it, he sees nothing. When he touches it with his arm, he feels nothing. So, the man thinks, "OK, one of my senses tells me the limb is there, but many other sense tell me the limb is not there. I assume, the first one sense tricks me."
A similar investigation will be conducted in case of illusion, or hallucination. And if I don't know whether the object I see is real, or not, I will ask others about it. And if they say that can see it too, I'll assume it is there.

So, there are generally two ways to obtain knowledge:
1. We perceive objects with our own senses.
2. We believe in concepts which we receive from others.

Pt. 2 seems to be a second hand tier knowledge, but even the pt. 1 bears its flaws. We know that perception is unreliable, and our trust in feels is just practical and can't be used to find out the truth. And the most depressing thing is, there is no other channel of information about the outer world for us.

>  >Causality requires a first mover, a cause which is "put in motion by no other", otherwise we would have a infinite regress of causes

Exactly! That's why the "first mover" can't be found within existence. If "the first mover" was there, that would imply he had to have a cause too, agree?
And non-existence to the rescue here, because unlike any existing object, non-existence does not require any cause for itself to exist, simply because it does not exist. And if we accept that non-existence and God are synonyms, wouldn't that make God even greater in our eyes? Look:
- God is the only source of all ever existed thing.
- God doesn't exist so, God can be own cause, and outcome, own alpha and omega.
- God doesn't need to exist, yet God makes it possible for everything to exist. And God absorbs everything at the end.
- God can't be comprehended.
- God is constant, it doesn't change.
- God is more than eternal, because God is the source of space and time.

And look, one doesn't have to be a religious man to proclaim all that points, those are sequential to the pondering about non-existence.
