Does the Big Bang Theory Contradict the First Law of Thermodynamics?

[onlyatheory]

How was the big bang possible considering the 1st law of thermodynamics. Was all energy and matter created during the big bang or was it previously somewhere else?

has the energy and matter from the big bang existed forever?

That is unknown and possibly unknowable. Under certain conditions, energy can spontaneously arise from 'nothing' [a quantum weirdness thing]. Here is a good video:

The first law of thermodynamics doesn't work in General Relativity.
