Discovered by: Discovered in prehistoric times Carbon is the most important building block to life. Oxygen (O) along with other elements help out too, but carbon creates DNA, proteins, steroids and more. DNA is especially important to life. If your DNA instantly disappeared, you would probably feel fine for a little while. The problem is that you’re not fine. This is referred to as the
