Atheism and the meaning of life - what drives you?

[Aegon]

Unless you have a painful terminal illness or you're being tortured or something, existence is always better than non-existence.

.. Perhaps have a go at explaining how you've reached this conclusion.   Imo non existence isn't an experience so may not be reasonably compared with any experience. 

I've always ben fond of this:

" I was not
  I was
  I am not
  I don't care"   (From an ancient tomb one the Via Apia not far from Rome)

Unless you have a painful terminal illness or you're being tortured or something, existence is always better than non-existence.

What is the justification for that proposition? What do you mean by “better”?

Pretty simple. Sunsets, good food, a perfect autumn day, getting head... all things you can't enjoy if you are not.

Perhaps I'm not deep enough in the philosophical weeds for this discussion?
