To know and to believe are two different things.
You may believe something about the unknowable, but you don't know it. 
Stop claiming otherwise.
And don't tell me that reading the book of bizarre Jewish mythology gives knowledge rather than belief. That too is unknowable.
The world might be a much better space with a little less certainty about its variety of invisible friends.
It has taken me a long time to know there is a difference between these different things. I was infected early on with the delusion.
Now I'll go back to fishing. My best wishes to each of you.
