Your posts are an example of the author's point. Massconservative tell us "[i]t is generally accepted within the scientific community". Hunble tells us he has referred to textbooks. I have to assume that you are both telling the truth (otherwise discussions on FR would be meaningless). Hunble cites sources. If massconservative can site sources other than the ethereal "they", then maybe I'll believe him. Until then, Hunble is more persuasive, and the author's point is bolstered.

Good comment and I was guilty of invoking a higher authority (text books) as you pointed out.

However, I have been rather busy in getting my two telescopes up to scientific quality lately so that I can study the spectrum of stars.

Spectroscopy is the science of studying light and identifying the elements. Each element, such as hydrogen, radiates at very specific frequencies, and by studying the light that is received from an object, you can calculate the relative quantities of each atom.

That is why I was rather surprized when it was stated that hydrogen, amonia and methane were not considered a major portion in the early Earth atmosphere.

Simply sampling the gases released from a volcano would prove otherwise, since obviously those gases are still trapped inside the rocks of the Earth.

Due to the low gavity of the Earth, light gases such as Hydrogen will eventually excape to space. Even a child knows that a balloon filled with hydrogen or helium will rise in our atmosphere.

For larger planets such as Jupiter, Saturn, Uranus, Neptune, the combination of a highter gravity and colder temperatures will keep the lighter gases.

This is not something that I must rely upon some text book, but is a subject that I can actually measure with my own telescope.

Jedi-Girl has demonstrated the purile arrogance so very needed by the credulous adherents of the religion of evolution . Real science be damned , logic be damned, evidence be damned ,the God of creation must be dethroned .The scripture is right "the fool in His (or Her) heart says there is no God.

The early atmosphere of the Earth contained oxygen, this would prevent the formation of amino acids and nucleotides, since atoms and molecules would bond with the oxygen atoms rather than with hydrogen. If some amino acids were formed, oxygen would cause them to decompose quickly and terminate further reactions could eventually produce life. The Miller-Urey experiments only work in the total absence of oxygen.

Even with the total absence of oxygen, life would not be able to self-organize. Without oxygen, there would be no ozone layer protecting life from the sun's ultraviolet radiation. This radiation would break down organic compounds soon after they were made. Basically a Catch-22 situation.
