I am against religion because it teaches us to be satisfied with not understanding the world.
There may be fairies at the bottom of the garden. There is no evidence for it, but you can’t prove that there aren’t any, so shouldn’t we be agnostic with respect to fairies?

The universe is not hostile, nor is it friendly. It is simply indifferent.
John Haynes Holmes, A Sensible Man’s View of Religion (1932)
