The Miller experiment, (more commonly known as the Miller/Urey experiment due to the great influence on Miller by his college professor Urey), is often attributed as one of the best evidences for the evolution of man in history. The experiment in essence brought about Amino acids(one of the building blocks of human life) in a “early earth” environment. I will use this post to bring to light some of the problems with the Miller experiment and expose it for what it is.

The parameters of the Miller/Urey experiment were to find out if life could have spontaneously generated in an early earth environment, he simulated what was thought to be the atmosphere of the early earth. This environment was composed with high levels of Ammonium, Hydrogen, Methane, and Water vapor. Any chemist worth his weight will tell you that these gasses do not react under natural circumstances, so in order to make up for this Miller added electrical current to the apparatus.(The early earth was thought to have been under constant bombardment by electrical storms at this point in time).
Now while Millers concotion did indeed make random amino acids in a jar, and evolutionists used that to mean that life could spontaniously generate, Millers experiment had several flaws.
Misconceptions.
Millers experiment formed 3 of 20 amino acids necessary for human life, however, a portion of the experiment commonly left out of the text books is how he got them.
Miller used a contraption called a cold trap
“In vacuum applications, a cold trap is a device that condenses all vapors except the permanent gases into a liquid or solid. The most common objective is to prevent vapors from contaminating a vacuum pump. Cold traps also refer to the application of cooled surfaces or baffles to prevent oil vapours from flowing from a pump and into a chamber. In such a case, a baffle or a section of pipe containing a number of cooled vanes, will be attached to the inlet of an existing pumping system. By cooling the baffle, either with a cryogen such as liquid nitrogen, or by use of an electrically driven Peltier element, oil vapour molecules that strike the baffle vanes will condense and thus be removed from the pumped cavity.”
In essence, Miller’s experimental atmosphere was not capable of sustaining the amino acids for an extended period of time. Miller knew this because in his other attempts without the cold trap(which are conviniently not oft mentioned) Miller could not successfuly make the amino acids. He was only able to sustain the amino acids by removing them from his concoction as soon as they were created by the use of the cold trap. I.E.) Using liquid nitrogen, Miller used the cold trap to freeze the amino acids as soon as they were created and removed them from his apparatus thru a vacuum.
This is a strong argument against Miller’s case considering as how he couldnt keep his amino acids alive without taking them out of his concoction.
Recently scientists have decided that the early environment was not the one which Miller used, they also state that the early earth was not bombarded with lightning as we had once thought. However they still find a way to assert that even if you changed around the atmosphere and removed the constant electrical current, you would still get some form of life building material.
Summary
So far I have not heard of a single successful experiment to create and sustain amino acids in the more realistic early earth environment. So with the flaws that have been found in the Miller/Urey experiment, I would think it is safe to say that we cant make life in a jar with gas and electricity.

wow, that’s some deep stuff.
pretty ironic that it was the “Miller”/Urey experiment huh!
btw…like the way you did your D!

The key thing that the Miller-Urey experiment showed is that it is possible to create complex organic molecules by chemistry alone, without positing divine intervention. Currently the thinking on the origin of life (as opposed to its subsequent evolution) centres on conditions around fumaroles (volcanic vents) on the sea floor, which provide a suitably chemical and energy rich environment, known to be home to bacterial colonies. Jury’s still out on that one though.

But the main thing that I see is that he didnt create complex organic molecules by chemistry alone. The use of the Cold Trap was basically Miller’s use of “divine intervention” within his system, otherwise his experiments failed to render the molecules. !)avid
