Not only is the universe infinite, but for all practical purposes what we have here on Earth is infinite. We may be running out of oil and fossil fuels (in some quite distant future), but they are compound molecules. We will never be running out of carbon (of which we have too much in the atmosphere), or hydrogen and oxygen, and of any element that has stable isotopes. Oh, and I'm aware Helium is not gravitationally bound by Earth. We will not be running out of that either (it's being continuously produced as alpha particles in the decay of Radon deep inside the Earth).
