The Miller Urey experiment was conducted in 1953. It was an experiment to see what kind of environment was needed for the origins of life. This important experiment revealed that amino acids, the building blocks of life, could be made under certain conditions.

These 'life in a test tube' experiments are taught at schools and colleges to this day as 'proof' of life coming from non-life without intelligence or engineering input. Of course, it was assumed that once the amino acids formed, every other stage in the emergence of life from non life though to humanity and beyond would follow automatically. This is still assumed, although not often talked about since no progress has been made and in fact they never got further than making a lot of poisonous and viscous liquids and very few unsuitable amino acids.

if substances now made by living substances could be formed in the conditions thought to have been existing in early earth.

THey put compounds that were found in early atmosphere and added a spark to see whether they could make amino acids which are essential to life.

The experiment was a success, and this proved that they could make amino acids in these conditions.

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.:)

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.

this experiment supported the theory of a ‘primordial soup’, the idea that complex chemicals needed for living things to develop could be produced naturally on the early Earth.
