They used an oxygen-reducing atmosphere made up of methane, ammonia and hydrogen to achieve the desired result. It is generally accepted within the scientific community that the Earth's early atmosphere did not have these characteriestics.

Who are the people in the scientific community that are stating the the early Earth atmosphere was not made up of methane, amonia and hydrogren?

Hydrogen is the most abumdant element in the universe, so derived molecules such as methane and amonia would be expected.

Funny, every astronomy book that I just looked at this morning stated exactly the opposite of your claim.

Is your statement another example of what the today's article was about?

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.
