With the small exception of a tiny bit of lithium made before star formation, yes.

  By what process was that Lithium created?

      Ok, completely unrelated, but here's a riddle: how many nuclear reactions are there in a thermonuclear bomb? 1. Fission of the plutonium pit 2. Fusion of a small amount of deuterium-tritium at the center of the plutonium pit (designed to be a source of extra neutrons to boost the yield of the plutonium fission) 3. Fission of Lithium-6. Yep, Lithium can undergo fission when bombarded with neutrons. It can't sustain chain reaction, but it's fission nonetheless. The main idea is to generate Tritium, which goes into the next phase, but the energy generated during the fission of Lithium is nothing to sneeze at. Pound for pound, it generates about as much energy as the plutonium. 4. Fusion of the hydrogen (tritium produced from the previous step, and deuterium that's stored in the form of Lithium Deuteride from the beginning) 5. Fission of a rod of plutonium in the middle of the cylinder containing the hydrogen (fission is returning the favor and boosts the fusion reaction) 6. Fission of the uranium temper. The main point of the uranium temper is to be heavy and contain the nuclear reactions for a tiny bit of time, so more generations of reactions can happen, but the secondary outcome is that some of the U-238 nuclei will undergo fission when bombarded by the neutrons from the inside of the bomb.

      Wow, I never knew that, thank you so much. So then, what are the chances of there being some primordial heavier than Helium atoms in your body? We may not be just 'star stuff', but some 'big bang' stuff as well :) (Probably would be anyway if you look at Helium and Hydrogen).
