Entropy of the universe is always increasing.

This does not mean that it is not possible for order to spontaneously be created.

However, when this ‘order’ occurs there must be the simultaneous occurrence of greater disorder in order for the entropy of the universe to still increase in accordance with the second law of thermodynamics.

 

This is seen in biology where the creation of an organism (eg a person) is due to particles being spontaneously ordered to create cells and functional biological systems. However, in order for this person to exist, other matter must be broken down (or become disordered). For example, while the person grows and maintains their ordered structure, food is broken down, and the heat released from their body will cause disturbances (or disorder) in the surrounding air particles, ultimately resulting in a net increase in disorder (entropy) in the system or ‘universe’
