Ashwin, I agree that everybody has the own thoughts and grown up with that thoughts. What i mean to say is discussion shouldn't stop when the person reaches to the thoughts he/she is seeking which found in other posts.

I agree with you on the question that if purpose of other creations is for humans only. There are so many trees, plants, creatures which is of not to use for humans at all albit a question if humans know their existance is the first question. So i am also doubtful on the link if all those creation is to serve humans and humans are to serve god.

But still Q remains what after serving the god. What next?

Additionally, what about the creation on other planets? And why there would be destruction in the world then?

(Note creation it have both meaning things without life and things with life)

The question is still there what's the purpose of human life? (as i said earlier the Q itself is unfathomable)
