You know it's not unlimited don't you. 4,500,000,000 years from now, the hydrogen will be all gone, then the sun will explode engulfing the Earth in a huge fireball. My son used to worry a lot about this.

There is one.

This one goes back to Orville and Wilber. "If god wanted man to fly we would be born with wings."

Or maybe he would have provided with photosynthesis as he did plants. But I guess he said , I made plants able to get their energy from my miracle. Now when I make man, my pride and joy, he has to consume freshly killed tissue to survive. I am freaking brilliant and need to rest now after seven days of hard work. Though I live in eternity, still seven days, it is exhausting and requires rest. Plants provide shelter and oxygen, but man , go kill for your meal.
