Perception of "PERFECTION" as god

"Isnt it amazing? " she said. " how nature is made!  its so perfect" ! she continued " GOD has made it so perfect"

I chuckled in obvious disagreement. The word GOD has always amused me. Provokes a thought on how it first came into existence , the word GOD.

" Dont you see it?  how perfect it is! the way things are. new life grows out of nothing! lives , takes energy from nature and perishes and this goes on! there is perfect harmony between everything.  who can imagine a big tree growning out of a tiny seed? leave trees take us for example"
i continued to patiently listen
" we r so perfectly made! we grow literally out of nothing. when we see we are just flesh and bones but there is something keeping us alive!  GOD made us like this
We are perfectly made to live in this world! even if there was a thing not like it is now we could not hav survived for example if we did not have some small bones in ears we could never stand on just two legs!  even science shows existence of god! " she took a neccesary deep breath as she finished her talk.
I was lost in the convo so much that i started to believe she was right!! And then i came to my senses my thoughts flew back.

i said " yes we are perfect! yes we are very much adapted to this environment thats why we live!  but where does god come here? "

she looked puzzled  , looking for more explaination from the athiest me . I continued " We are this perfect because we changed,  we learnt we adapted.  Thats what darwin taught us!  we hav a perfect nose because the ones with an imperfect nose perished! nose being a small example.  consider giraffes ! one when sees a giraffe in a forest with long trees would say -GOD has made giraffe's neck so tall so it wont die of hunger in these forests with tall trees all praise the lord blah blah amen- But what actually happened is there were giraffes with shorter neck! when vegetation at lower levels was not much available giraffes started to adapt by having longer necks! so the ones with longer necks survived and the others perished!  that is the PERFECT ones survived!  "

I could see some kind of approval in her face but i still went on

" so what we see in todays world are the fittest survivors or the PERFECT ones, that is why we see it like a perfect world created by some miraculous mighty force. But the truth is nature itself is the architect.  it does all sorts of trial and error techniques to bring out perfect ones,  so this amazingly awesome perfection of nature is what i think was referred to as GOD "

The convo ended with a hint of smile on.my face and a convinced lady at the other end.
