I totally agree with Slarty.
The difference between people who believe in a higher deity and people who don't, is in general that the non-believers don't need to have an answer to everything.
(believer)If I can't think of a logical explanation then it must be something higher, something supernatural, how else can you explain it?
I accept that I don't understand everything. I don't have an answer to all questions. That just means that I don't know everything.
I don't understand how the tv actually works.
But it's not supernatural.
There are things in nature that I don't understand, but that doesn't mean it's supernatural.
I don't know why I'm alive, but I've decided to give it a reason myself and make the best of it.
The unknown is not that scary, just accept it.
I don't need a God to fill in the dots.
