the zeroth law was introduced after the first and the second law
however it gave the fundamental basis for temperature and hence was named the zeroth law

Zeroth law is different from first law of thermodynamics.
Zeroth law is if system A and B are in equilibrium, and B and C are in equilibrium independebtly tehn system A will be in equilibrium with C.

First law of thermodynamics is regarding the conservation of energy in universe and enrgy ca only be converted from one form to another but neither it can be destroyed nor it can be created.
