Couldn't agree more - I wasn't thinking about how that might be interpreted when I wrote it..... Absolutely we ask "why" - and look for explanations. I meant nothing with regards to being defeatist and not looking at things - only that, as far as I can see, even though we'll keep going deeper and deeper and discovering more and more, we'll never get to a final answer (other than perhaps getting to a point where we can't research further without blowing up the universe? I read too much sci-fi.

A final answer would be boring..... WHY is a fantastic question - it's just not something pure science can answer with finality, only layers until we get to an unknown.
