make up life so we know that life probably could have been created like this.

Stanley Miller and Harold Urey carried out some experiments in 1952 and published their results in 1953. The aim was to see if substances now made by living things could be formed in the conditions thought to have existed on the early Earth.

The two scientists sealed a mixture of water, ammonia, methane and hydrogen in a sterile flask. The mixture was heated to evaporate water to produce water vapour. Electric sparks were passed through the mixture of water vapour and gases, simulating lightning. After a week, contents were analysed. Amino acids, the building blocks for proteins, were found.

of an experiment that had taken place a year earlier. The scientists sealed a mixture of water, ammonia, methane and hydrogen in a sterile flask, to simulate the conditions on planet earth 4 billion years ago. The mixture was heated, and the water evaporated. Electric sparks were passed through the mixture of gases, simulating lightning. After a week, amino acids were found.

This is significant, because animo acids are the building blocks of proteins, and so the experiment supported the primordial soup theory, which is the theory that the chemicals needed for life to form could be found naturally on earth

A scientist called Hazen encased a tiny amount of water, a chemical called pyruvate, and a powder that produces carbon dioxide, in 3 non-reactive gold capsules. He heated the capsules to 480 degrees and pressed down on them at 2,000 atmospheres. When he took the capsules out two hours later, the contents had turned into tens of thousands of different compounds. In later experiments, he combined nitrogen, ammonia and other molecules plausibly present on the early earth. In these experiments, Hazen and his colleagues created all sorts of organic molecules, including amino acids and sugars.
