Your science is wrong. Water vapor is indeed a potent greenhouse gas, but CO2 also matters. Consider the fact that even in arid deserts, it does not get as cold at night as it does on the moon. Why would that be? Right. The atmosphere blocks, to some extent, the radiation of heat back to the sky. And what part of the atmosphere does that? The CO2. It's not as insignificant as you think.
