Higher air pressure and oxygen levels in ancient times?

I hear Creationists mentioning it alot but never any actualy support of it...

 

Can anyone please fill me in?

Carl Baugh is one of those promoting this. The idea is that the atmosphere originally had more oxygen and pressure, thus supposedly supporting a lot more life and larger animals, particularly the dinosaurs. 

Partly it is also supposed to be a result of the theory of the "dome" of the firmament and the "water canopy".  This would supposedly be a testable deduction from that.

So it's all in their fantasy?

No scientific proof etc.

Remember that "proof" is strictly speaking not available by science.  Let's say no publicly available data.  Baugh claims supporting data, but no one has ever seen it.   

Higher oxygen pressure would have made for some interesting campfires but they would have been over pretty quickly. I hate think what the forest fires would have been like. As far as I can tell Baugh has no supporting data for anything he claims.

Couple things pop in my mind right away.

1. The caustic effects of the high oxygen should be obvious to geology.
2. I know air samples are frozen in the glaciers and ice sheets, this should prove any period of high oxegen levels.
3. The high oxygen levels would cause faster aging due to increased metabolism and free radicals. This is contrary to the OT.
4. Increased preasure would have greatly increased the amount of heat retained from the sun, much the way Venus does today. This most certainly would have had an increase in global temperatures making the middle east a barren desert at that time.

Man, I'm not even a scientist. Do people actually believe this guy?
