Stanley Millers failure

In 1953 Stanley Miller passed an electric spark through an “atmosphere” 
of hydrogen, methane, ammonia and water va****. This produced some of the 
many amino acids that exist and that are the building blocks of 
proteins. However, he got just 4 of the 20 amino acids needed for life 
to exist. More than 30 years later, scientists were still unable 
experimentally to produce all the 20 necessary amino acids under 
conditions that could be considered plausible.

Miller assumed that earth’s primitive atmosphere was similar to the one 
in his experimental flask. Why? Because, as he and a co-worker later 
said: “The synthesis of compounds of biological interest takes place 
only under reducing [no free oxygen in the atmosphere] conditions.” Yet 
other evolutionists theorize that oxygen was present. The dilemma this 
creates for evolution is expressed by Hitching: “With oxygen in the air, 
the first amino acid would never have got started; without oxygen, it 
would have been wiped out by cosmic rays.”

  The fact is, any attempt to establish the nature of earth’s primitive 
atmosphere can only be based on guesswork or assumption. No one knows 
for sure what it was like.

How likely is it that the amino acids thought to have formed in the 
atmosphere would drift down and form an “organic soup” in the oceans? 
Not likely at all. The same energy that would split the simple compounds 
in the atmosphere would even more quickly decompose any complex amino 
acids that formed. Interestingly, in his experiment of passing an 
electric spark through an “atmosphere,” Miller saved the four amino 
acids he got only because he removed them from the area of the spark. 
Had he left them there, the spark would have decomposed them.
