How would one argue against the argument of entropy proving the existence of God?

Not sure if this is the right place for this question, but I’m just curious what the normal counter argument is for this topic. The original argument is as follows (put very simply because I don’t feel like going through sources and stuff) for those who may not be familiar:

The second law of thermodynamics essentially states that entropy, or the amount of disorder in a system is always increasing. An example would be for a cup of hot coffee that when put into a closed room would eventually become the same temperature as its surroundings because that is the lowest possible energy state

The argument then comes that for a system that has gone in for an infinite time, we would have to then be in a state of complete disorder, or nothingness, the lowest possible energy state, unless something else were to give the energy to start it at a higher energy state. By this, I mean in the case of the coffee, there has to be energy exerted into the coffee to heat it up in the first place. In a closed system (the universe), something would have to put the universe into a higher energy state to begin with to allow it to then become a more and more disordered universe until there is nothing.

I know one argument could be that this simply proves that there was a Big Bang, but wouldn’t there still need to be some cause to the Big Bang? According to the second law of thermodynamics, it seems like there could not just be a completely closed off, lowest possible energy state that just gains energy out of nowhere
