Atheism can be a religion. It just means you are skeptical. Perhaps Cecilia does believe in paranormal? (Things currently unexplained)
Some people deny everything, some people are skeptical and some people are gullible.
It is fine to follow the rules of your religion unless it becomes quite deluded, but then that is why there are a lot of sheeple.
The CO2 debate is the current delusion of sheeple. (I'm not a denier, but I think future technology and/or reducing the birth rate is better than sending society back to the stone age.)
