Just Think and Ponder ...

We are so engrossed by the means which surround us that we rarely stop and think at some issues which have no answer at all. For example when we pour some water in a glass we don't think the whole system of 'nature' which has already done its job so that we get clean water to drink. Or for example when we pump gas in to our car , do we ever think of the process which has gone into 'manufacturing' the oil? All mankind did was to just purify or process the extract, but how did 'nature' know the needs of mankind millions of year before when 'it' started 'manufacturing' oil.
