If the 4.5 billion year history of the Earth is equated to one year, Man as we know him today (Homo sapiens) only arrived on 31st December at 11:45pm! The Earth was formed 4.5 billion years ago. If we say that the thickness of a single sheet of paper is equivalent to 1,000 years, to represent the age of Earth we would have to build a pile of paper 450m high (one and half times the height of the Eiffel Tower)!
The Christian era (from the birth of Jesus Christ to present day) would only take up the last two sheets of paper in the pile!
As far as the formation of the Serre de l’Ane site is concerned, the “sheet of paper” is about 13m from the top of the pile.
