Organic compounds can be formed without the existence of life. Take a look at Saturn's moon, Titan. It is chocked full of organics. Organics, including amino acids, have been found all over the solar system and in interstellar space.
Ok, but do you realize that there is a controversy about the source of "fossil fuels?" Some are saying that it is formed by the earth itself. Others claim that the existence of organic compounds in the crude PROVE that it is from decaying life.
So, are organic compounds common without the existence of life or aren't they?
