Why does life exist?

From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat.

This could mean that under certain conditions, matter inexorably acquires the key physical attribute associated with life.” says Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology.
