Thoughts on Entropy

It was recently brought to my attention that a present atheistic argument against the use of entropy to show that the universe has a beginning and hence a beginner runs something like this.

Areas of low entropy can clump together resulting in a temporary localized inversion of the general trend of the universe towards a point of low energy (high entropy).

Forgive me for stating the obvious, but even if this is true it says nothing about how these areas of low entropy come to exist at all.

The point of the argument from entropy is that in a eternally old universe all available energy would be exhausted. There would be no clumps of low entropy because there would be no low entropy.

Only a finite universe with an actual beginning would have these areas of low entropy able to clump.
