I know that there are no gods.

[Edwardo Piet]

If you are defining knowledge as awareness, than how can you 'know' that that are no gods?

I don't know how I can know. I just claim to know. Maybe I am aware (maybe I know) maybe I am not. Maybe what I am aware of is the absence of God, maybe not.

To know that there are no gods would be to be aware of something which is non-existance..

Yes, which is simply the absence of God(s) in this case.

and if you are aware of it, it would stand to reason that it does exist.

Yes. If I was aware of God, God must exist.

Of course, you could answer that you are aware of the universe's apparent lack of gods, but to do so would be to claim awareness outside of yourself, something we might all agree that you cannot claim to have without proper proof outside of your own testament.

I claim such awareness because I consider God to be improbable. Since God is improbable I am probably aware of his absence rather than aware of his omnipresence in all things. That's why I claim to be aware of his absence rather than his omnipresence.
