I know, “been there done that.” Lets do it again…

The idea came from an environmental thread I posted in where I referred to a tree as a device or gift that regulates the earths oxygen produced by the oceans.

Anyhoot, since the earths been turning she’s had an oxygen level of ~21%.
We know that trees don’t release oxygen at a constant, yet you can go anywhere in the world and observe oxygen constant at ~21%. Personally I suspect land based plant life is responsible for the regulation thus a device having been designed.

The thread isn’t about trees, but I’d like to discuss the certainty of how Darwinist believe things like, “how mother nature knew there were smells so she could design us a nose” and sh_t.

go to the tallest mautain and tell me that there is as much oxygen there as down here

Okay. We'll discuss how you think a magical man in the sky made us so we could be blindly faithful to him and give him blowjobs on demand.

~Dr. Martin Luther King, Jr.

"Mother Nature" don't know nothin'. Trees are not made to regulate oxygen. Trees were not "made" for anything. They were the result of genetic selection and attrition resulting in an organism that uses sunlight and CO2 to create Glucose, which it then utilizes ("burns") to release energy and, in the process, oxygen and H2O.

The atmosphere is 21% O2 because that's the level where the factors of biological O2 production, biological O2 consumption, chemical recombination, and probably things that I don't understand reach a stable equilibrium. This happens to be just right for the animals living on the Earth's surface because those animals are evolved to use the oxygen present, which is 21%.

We have a nose because some distant ancestor of mankind at the cellular level had a set of proteins designed to detect certain chemicals and other proteins as a survival instinct. As life evolved, a similar concept formed for multicellular organisms. Being able to detect changes in what chemicals are present in the air is a natural survival trait. Also, since the cavity where air is pumped into the lungs is naturally exposed to great quantities of air, it was the natural location for a chemical sensing organ. Hence, a nose.

The reason Intelligent Design believers don't "get" evolutionary theory is because they assume right off the bat that something designed everything. Even when you state that your theory is based on there not being an intelligent designer, they continue to subconsciously assume one (hence the "mother nature" comment).

The phenomenon in fact is used in formulas as a constant in providing passenger aircraft with 15 or more ft3/min per passenger of outside air +/- what’s recycled to save fuel (I‘m a single engine private pilot.).

In short, @10,000 feet the oxygen quantity is 50% that of sea level but still consists of 21% concentration.
It’s pretty much the only constant occurring in nature as much as it being the only thing needing to be constant. If oxygen were random and we evolved from goo, are lungs would not be what we have today.

they aint, if it was then there wouldnt be anything called blooddoping

Oxygen is not random because of a little phenomenon called diffusion. In a mixture of gases (such as the atmosphere), all gases present will diffuse until they are of approximately equal concentration throughout the mix. For example, if you're in a car with someone and they fart, there will be a very high concentration of fart-gas around the person for a few seconds, but the gas will diffuse throughout the car within a few seconds or minutes, becoming lower in concentration as it goes.

In fact, though, oxygen concentration in the air varies minutely due to conflicting air masses; not by huge amounts, never more than about 1% and rarely that, but it does vary. And as you go higher in elevation, oxygen concentration does go down. In fact, once you get out of the troposphere, oxygen levels start to decline rapidly; by the time you reach the upper thermosphere, the main constituents of the atmosphere are hydrogen and helium with small amounts of nitrogen and other gases, including monatomic oxygen and ozone, which is formed by solar radiation knocking off electrons from O2 molecules, causing unstable ozone and monatomic oxygen to form.

And if oxygen did, by some phenomenon, vary more than it does (by more than 5-10%) then our lungs would be different, through natural selection preferring those with lungs that could handle the wild changes in atmospheric composition without ill effects.

If you want to support the notion of intelligent design then you have been terribly misled on what it's all about. Trust me, you don't want to go there. It was never properly thought out and it causes more problems for Christians than it's worth.

Hey, the Nuremburg rallies transported to the 21st. century! You Americans just don't get it yet do you.
