The Miller-Urey experiment led to the creation of amino acids from water, hydrogen, methane, and ammonia. These amino acids were 13 of the 22 that make up protein in cells. The carbon in the methane was turned into amino acids from the experiment that was meant to imitate primordial Earth. Sydney Fox found that amino acids could spontaneously form peptides. Of course, both of these assume a model of ancient Earth that has not been agreed upon by science.
Francis Crick (from the singing duo Watson and Crick) says that life may have come from Mars. The hypothesis reasoned that Mars cooled faster, so life would me more possible there in the beginning. The fact that there are organic compounds throughout the universe helps this idea, but it assumes Mars was bombarded with asteroids and comets and the compounds survived all the way until they reached Earth.
