Atheism not only denounces the existence of God, but by its own definition denounces the principle by which it criticizes the reality of God. To make an absolute statement in the negative is similar to saying that nowhere in the universe does there exist a flying spaghetti monster. For the atheist to make such a claim he must have unlimited knowledge of this universe. What the atheist is fundamentally saying is that he has infinite knowledge of this universe to affirm that there exist no being with infinite knowledge. It is self defeating.
What a load of crap. Atheism doesn't "denounce" anything. Again, this seems to be based on the premises that (a) Atheists are an organization like the ones theists join, (b) all atheists are somehow united in the same way of thinking as the WT brainwashes people to be, (c) atheists compare notes, get instructions or are aligned with each other and believe the exact same thing (d) atheists are "against" or "anti" something, or (e) we simply refuse to listen to anything other than what reinforces what they believe. All that is just nonsense.
Sweetie, it is very simple. We don't need to prove the non existence of God, we don't need to prove anything to you, and for that we don't need a bible, nor a congregation, and certainly not "unlimited knowledge of the universe", whatever that means, anyway to feel confident in pour non-believes. Get over it.
