      electrons, up quarks and down quarks. Everything on the planet is made of these three particles. Air, cheese, people, rocks, everything.

      and why not – it’s a valid answer!!

      You could say carbohydrates, proteins, lipids and nucleic acids if you want to go to a smaller scale

      To go smaller you could say atoms……

      If you want to know the chemistry, by mass we are:

      Oxygen 65%
      Carbon 18%
      Hydrogen 10%
      Nitrogen 3%
      Calcium 1.5%
      Phosphorus 1.2%
      Potassium 0.2%
      Sulfur 0.2%
      Chlorine 0.2%
      Sodium 0.1%
      Magnesium 0.05%
      Iron 3.8g in men, 2.3g in women
      Cobalt, Copper, Zinc, Iodine < 0.05% each
      Selenium, Fluorine < 0.01% each

      So that's what you're made of!
