I believe, Energy is, what existed before the existence of time. The laws like conservation of Energy were imposed on the eternal Energy by nature/ God. Then some part of it got condensed into mass. Mass & the energy surrounding it (within the dimensions of space) were bound by those laws (Second Law of Thermodynamics) to give rise to CHANGE that was the birth of TIME. That is why we can't know the absolute entropy, but only the 'change in entropy' (this limitation, I believe, is due to the existence of Time).
Since then all the elements are moving towards randomness, following the Second Law of Thermodynamics..
