Chrystalclear. Do you know where oil comes from? We all know its underground, but how did it get there. Its often glibly stated that it is a by-product of the decomposition of organic matter laid down in prehistoric times... a liquid version of coal. There is however not a scrap of evidence to support this. No fossil remains are found in oil, or in close and common association with it. It can be found almost anywhere on earth. There is a convincing body of unprovable theory (no more unprovable that the currently accepted ideas) that it is a kind of natural exudate from deep within the earth. This means that while it may get harder to find, it will never run out, for it is replenished continuosly, but slowly.
Makes you think doesnt it. ps. dont believe all that oil running out stuff. Theres more oil still in the north sea than we decalred back in the 70's
