Suzy,
When we make a claim, we are generally willing to back it up with evidence. The "evidence" for gods is apologetics, which from my experience is based on some combination deception, logical fallacies, or emotional manipulation.
I don't know of any atheist that claims our lives have ultimate meaning. If you're looking for that here, you're looking in the wrong place.
"You just replace gods with reason and you get cranky and call others anti-intellectual." Reason and science have given us, among other things, the computers that you've used to write this node and read mine. Science works. Religion, not so much.
