In 1953, Miller filled a flask with water, methane, hydrogen, ammonia then zapped it with electricity--building blocks of life!

In 1953 a student named Stanley Miller did an experiment showing that the simple chemicals present on the early Earth could give rise to the basic building blocks of life. Miller filled a flask with water, methane, hydrogen and ammonia—the main ingredients in the primordial soup. Then he zapped the brew with electricity to simulate lightning, and, voila, he created amino acids, crucial for life. Now, scientists have reanalyzed this classic experiment, and found that the results were even more remarkable than Miller had realized.
