question about the MEANING of all EXISTENCE is the wrong question.
Nature does not intend anything when it makes birds colourful and
iridescent and flowers blossom in all colours. All the beauty and
fascination is not directed towards a meaning nor is it planned or
deliberate. It is solely the purpose that determines the events.
Organisms developed because of their function... Fins are caused by
water and wings by air... Only when the purpose had been fulfilled did
organisms remain. Only in retrospect does it lead one to assume
some meaning in everything. We would like to know this meaning – but
it does really not exist!
