NDEs and Evolution

Playing devil's advocate here ... As far as I am aware, evolution is a purposeless process and any survival value is just a bonus, so there is no point in looking for a purpose.  Instincts, although being complex, are built on a simple sliding scale: we run from death, fear and pain towards life, happiness and pleasure.  Given this, an evolutionary mechanism to make the passing into death easier might serve as an explaination. 

I don't believe in much of what I just wrote, and I leapt from purposeless evolution to having a purpose (just like evolutionists do ), but this would make some kind of loose sense to me if it wasn't for other evidence.

Is there an interpreter in the house?
