The reanalysis of a 1958 experiment suggests that volcanic eruptions may have spawned the amino acids that contributed to the rise of life on earth
Scientific debates don't get much hotter than the one surrounding the origin of organic molecules at the dawn of life on Earth. New findings, based on a reanalysis of a 50-year-old experiment, suggests that ancient volcanic activity was the source of the very first amino acids.
In the 1950s, Stanley Miller and Harold Urey of the University of Chicago performed a series of "spark discharge" experiments, in which the researchers applied electrical sparks-- meant to simulate lightning -- to a mixture of gases in steam-filled flasks. As the heat inside the flasks rose and the sparks flew, solids were produced and were captured in vials that could be stored for later analysis. Amino acids were formed in these reactions and they provided support for Miller's hypothesis that organic molecules could be formed from inorganic gases.

Holy Cow! L. Ron was right!?
No, in his SF books it was 75 million years ago that Xenu landed. LOL!
One spark-discharge experiment using radioactivity ran all night and in the morning the vessel was found broken open. Little footprints of black goo led to the window and a note was left........ What did the note say?
It's pretty much the same all over. Look at metallurgy. Sure, they've figured out some interesting stuff, but it basically just worthless crap, because it doesn't tell us where the metal came from.
Just tell me where the gold comes from and I’ll go get as much of it as I can.
Information is created by a mind. A metallic crystalline structure has symmetry and regularity, but that isn't information.
Sorry, can't help. I could say "It comes from volcanic eruptions and vents", but that doesn't answer the question, because it doesn't tell you where it came from before that.
That's true. Without a mind to organize and analyze it, it's just data.
Type II supernovae of between 40 and 80 solar masses. It happens during the collapse. Don’t get burned trying to get it!
“Well, Bobby, another one of those big questions for Mr. Science. ‘Can volcanoes produce life?’ Hmmm. You know the Mr. Science motto, ‘Doing Is Knowing!’ We have here a bowl of boiling cheese-dip to simulate the lava in a volcano. Here is our bottle of hydrogen and a sparkler to simulate lightning. Just a second. The court order requires that the fire department be notified whenever I conduct an experiment. Have we done that Director Lisa? OK! Here we go. We turn on the hydrogen...and put the lit sparkler over the cheese. HOTCHEESE!!!HOTCHEESE!!!HOTCHEESE!!! Thanks Cameraman Steve. That cheese-lava can really scald you. Once again, science triumphs over superstition! ‘Can volcanoes produce life?’ The answer is no, volcanoes can produce third-degree burns. Mr. Science has been receiving letters requesting him at birthday parties. The District Attorney has threatened to throw Mr. Science in Jail ‘until the end of time’ if he works at any more birthday parties. I will be at the Harrison Avenue Mall this Saturday from noon to four demonstrating volcanoes. Free nachos, too!”

This is as likely as a Boeing 757 being left behind after a tornado sweeps through a junk yard. And this theory fails to account for the information required to assemble amino acids into proteins. And, it fails to account for teleonomy and autopoiesis. I will invoke Polanyi’s Impossibility here!
