Summary

Is there an adventure, a drama, a more exciting suspense than that offered to us by the laborious research of the scientist on the lookout for the great secret of his origins? The film begins at the extreme limit of this noble uncertainty. Thirty million centuries ago. Three billion years. Already two proposals are offered to this uncontrollable search: the Earth will warm up or cool down? These first images, which represent the consent of the majority of scientists, attempt to show us the thermal fluctuations which govern the formation of this puffy meringue which will solidify: the earth of men.
