In the 1950s, scientists Miller and Urey conducted a classic experiment in which water, methane, ammonia, and hydrogen were sealed in a flask containing a pair of electrodes. An electric spark was fired between the electrodes, and after a week's time, they found that amino acids were present in the flask. Which of the following best explains the significance of this experiment in explaining the origin of life on Earth? Highlight the answer
A. It showed that any raw materials could produce the compounds necessary for life to exist on early Earth
B. It showed that life must have started somewhere else since organic compounds only come from living things. C. It showed how biological molecules can be formed from the very simple molecules that were available on early Earth
D. It showed how lightning can cause organic matter to decompose into amino acids, which were the first molecules on early Earth
