"Since we know that God exists..."
Whoa! Back up the bus. We know no such thing. You may hope God exists, you desire it, you may even think God really does exist, but we don't know that. In fact, if we use the Bible as a credible source (I know, I know) it shows that the God of the Bible cannot exist.
"and that fact to be certain simply because without God we CAN’T KNOW ANYTHING,"
"that is the very reason why we are on this blog trying to help Atheists realize this."
You have not even stated your case well, much less proved your point. All that I've come to realize from your post is that you're not so bright.
