It’s ironic to me the the smartest people on earth don’t get it when God took the time to write the answers down in a book for them.
It is because they believe they know better than God.
They insist on rejecting Him.
They want to be god.
The Miller/Urey Experiment...There has been a recent wave of skepticism concerning Miller's experiment because it is now believed that the early earth's atmosphere did not contain predominantly reductant molecules. Another objection is that this experiment required a tremendous amount of energy. While it is believed lightning storms were extremely common on the primitive Earth, they were not continuous as the Miller/Urey experiment portrayed. Thus it has been argued that while amino acids and other organic compounds may have been formed, they would not have been formed in the amounts which this experiment produced.
Cruising Chemistry
Many of the compounds made in the Miller/Urey experiment are known to exist in outer space. On September 28, 1969, a meteorite fell over Murchison, Australia. While only 100 kilograms were recovered, analysis of the meteorite has shown that it is rich with amino acids. Over 90 amino acids have been identified by researchers to date. Nineteen of these amino acids are found on Earth. (table showing comparison of Murchison meteorite to Miller/Urey experiment) The early Earth is believed to be similar to many of the asteroids and comets still roaming the galaxy. If amino acids are able to survive in outer space under extreme conditions, then this might suggest that amino acids were present when the Earth was formed. More importantly, the Murchison meteorite has demonstrated that the Earth may have acquired some of its amino acids and other organic compounds by planetary infall.

After about a week of operation, a dark brown scum had collected in the lower flask and was found to contain several types of amino acids, including glycine and alanine, together with sugars, tars, and various other unidentified organic chemicals.

That’s right, see #22. :’) The search link also has more info about M-U, regarding the other two parts of the experiment.
If I were to take a BLT sandwich and expose it to lightning how long would it take to create life? Surely a BLT contains most if not all of the building blocks of life.
If the creation of life can be traced to one event where the building blocks were lined up just right by some force. Why hasn’t the formation of life been repeated in nature in the billions of succeeding years when the building blocks were much more prevalent?
Did Volcanoes Spark Life on Earth?
ANSWER: NO.
Life came from somewhere else, just as the earth came from somewhere else.
see #25 for your answer...
That answer just kicks the can down the road a little bit.
“These experiments support the hypothesis that a biochemistry based on RNA alone preceded the familiar biochemistry based on nucleic acids and proteins.”
In that the only difference between DNA & RNA is that the backbone sugars (Ribose)is only different than the sugar deoxyribose of DNA in that it (deoxyribose) is missing an oxygen at the 2’ position and that the nitrogenous base Uracil is substitued for Thymine found in DNA. That doesn’t surprise me at all.
However, the original questions was about the zapped methane, hydrogen, and ammonia in the old experiment in the 50s that produced amino acids.
