To the question of does God exist, the answer is whether Intelligence created Life

[Paleophyte]

And thus everything, both intelligent and non-intelligent, is made of energy of one form or another. From that, it is trivial to deduce that energy alone is insufficient to explain intelligence. The rules of energy alone won't be enough, so arguments from thermodynamics will be insufficient at best, and completely wrong at the worst.

In a complex system like the universe, the first important thing is to realize that we humans are made of energy. When we realize this, then we can start looking for the complex!

We have already realized that. Your explanation remains insufficient. It's as meaningful as using thermodynamics to explain the rules of hopscotch. The children and the chalk are both just forms of energy, so it should work.
