Your question predisposes the existence of a God.

As an agnostic, my response is: I don't know and I don't care.

I can't say with absolute 100% certainty that tiny invisible gnomes don't live under my house and wage an unending battle against tiny goblins that are trying to invade my home and steal all of my cookies.

But I think that the possibility of such a thing is so ridiculously minuscule that it can be completely dismissed as nonsense.

And though I can't say with absolute 100% certainty that I know that there is no god (or gods) I can dismiss the existence of any god or gods as so extremely unlikely that it's utterly irrelevant.

You're either an atheist or you're not.

God is a construct born from ignorance. I don't deify the unknown.

If you want to hide an elephant in a room full of agnostics just call it God and it will be invisible to them.

Do you believe that nothing is known or can be known about the existence or nature of leprechauns, unicorns, Zeus, Thor, pixies, fairies or pillowpants the hymen troll who bites the willies of people who try to fuck unmarried virgins?

There has been no verifiable evidence that I know of that indicates the existence of any deities other than collections of fables that were intended to instill fear in exchange for obedience.

You must first define which god that you are talking about before your question can make any sense.

As far as I know, I have personally never found anything out about him, but he may show up tomorrow. Just not holding my breath.

PS. Beware fakes, there are a lot about, every religion seems to have one. It may be best to avoid those, since if the real one does turn up, she/he/it may be annoyed.

That which does not exist, cannot be known outside of fiction.

A god is not defined by reality or existence, believers make the assertion that it is, the god makes no assertion whether it exists or not, it is therefore the believer who must then PROVE the assertions they make.

Agnosticism is irrelevant. Everyone is agnostic, including theists. They, like everyone else, DO NOT KNOW definitively if a god exists, that is why agnosticism is irrelevant.

In order to know, you must have knowledge, in order to have knowledge, you must have evidence. Believers believe without evidence producing knowledge. An atheist, or non-believer, accepts knowledge that evidence produces. Theists have NOT produced any evidence for gods.

This is why atheists, or non-believers, demand proof in order to obtain knowledge and theists demand belief in order to sustain their faith.
