Illogical. Nothing is always nothing; it's never something or anything. Frankly, "nothing" is an abstract concept at best. I think you should refer to it in the opposite, ie, "There was not anything to see", rather than "There was nothing to see."
"I have nothing". What's that? You say you have something, either an idea or a physical entity. But in actuality, nothing is neither of those. Instead you should say "I don't have anything."
And lastly, you can't "see nothing," as in "I see nothing there," because there isn't anything at all to see. To say I "see nothing" means first you see something, but nothing is never something, so you should really revise that statement to instead read, "I don't see anything."
