No. Some plants grow underwater. Sorry.

Nope. Beats me.
Allowing the survival of a species via the ingestion and defecation of another is true evidence of divine intervention.

I'm not here to argue against arguments using the argument of what you consider an 'authority'; thr fact that you didn't make an actual argument from my comments is an indication you don't have one. I can read a book or search the net for what you are proposing, don't need your help there, lol.

Mainly asking for a clarification of what you said before, since I think I must be misinterpreting what you were saying.
Basically, you seem to be going for 'oxygen is required for life, and oxygen comes from life'. But actually, oxygen is not required for life. Many anaerobic organisms exist, including many which cannot survive in the presence of oxygen. You even have some in your gut.
Some of these anaerobic organisms are capable of producing oxygen through their metabolic processes. Cyanobacteria, primarily.
As oxygen levels increased in the atmosphere as the result of the proliferation of such organisms, some organisms adapted their metabolic pathways to make use of this new resource.

No, it wasn't about oxygen.
Please read the previous posts and i have a point about air as needed for humans and for the plants, and i didn't say needed for life. but they didn't even answer my question.
OK, then I read too much in to what you were saying.
Would you mind clarifying what the point you're making is? I read the other posts you made, but I think you were still working towards it.

Yes right i didn't complete because i think they know what i were going to and hence they refused to debate.
Well, I am willing to debate. So would you tell me where you going to?

The fairy godmother of course!
But... but... Darwin didn't exist. He's just a hoax, invented by the EAC (Evil Atheist Community).
No, Darwin was a incarnation of the One True Non-God on Earth! And Dawkins is his Prophet in our age!

It is about answering my questions, most part of air is consisting of nitrogen 78% and Oxygen 20%
Where do you think Nitrogen came from, origin of Nitrogen ?
Where Oxygen came from,origin of Oxygen ?
Which first formed and existed in earth atmosphere, Nitrogen or Oxygen or both instantly ?
Sapiens
Polymathematician
Air is a non-technical term for the mix of gasses in the atmosphere. It varies with time, place, altitude, etc. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.
Wiki clarifies that question:
Earliest atmosphere
The first atmosphere would have consisted of gases in the solar nebula, primarily hydrogen. In addition, there would probably have been simple hydrides such as those now found in the gas giants (Jupiter and Saturn), notably water vapor, methane and ammonia. As the solar nebula dissipated, these gases would have escaped, partly driven off by the solar wind.
Second atmosphere
The next atmosphere, consisting largely of nitrogen plus carbon dioxide and inert gases, was produced by outgassing from volcanism, supplemented by gases produced during the late heavy bombardment of Earth by huge asteroids. A major part of carbon dioxide emissions were soon dissolved in water and built up carbonate sediments.
Water-related sediments have been found dating from as early as 3.8 billion years ago. About 3.4 billion years ago, nitrogen was the major part of the then stable "second atmosphere". An influence of life has to be taken into account rather soon in the history of the atmosphere, because hints of early life forms are to be found as early as 3.5 billion years ago. How Earth at that time managed a climate warm enough for liquid water and life, if the early Sun put out 30% lower solar radiance than today, is a puzzle known as the "faint young Sun paradox".
The geological record however shows a continually relatively warm surface during the complete early temperature record of Earth with the exception of one cold glacial phase about 2.4 billion years ago. In the late Archean eon an oxygen-containing atmosphere began to develop, apparently produced by photosynthesizing cyanobacteria (see Great Oxygenation Event), which have been found as stromatolite fossils from 2.7 billion years ago. The early basic carbon isotopy (isotope ratio proportions) is very much in line with what is found today, suggesting that the fundamental features of the carbon cycle were established as early as 4 billion years ago.
Earth’s dynamic oxygenation evolution is recorded in ancient sediments from the Republic of Gabon from between about 2,150 and 2,080 million years ago. These fluctuations in oxygenation were likely driven by the Lomagundi carbon isotope excursion.
Third atmosphere
The constant re-arrangement of continents by plate tectonics influences the long-term evolution of the atmosphere by transferring carbon dioxide to and from large continental carbonate stores. Free oxygen did not exist in the atmosphere until about 2.4 billion years ago during the Great Oxygenation Event and its appearance is indicated by the end of the banded iron formations. Before this time, any oxygen produced by photosynthesis was consumed by oxidation of reduced materials, notably iron. Molecules of free oxygen did not start to accumulate in the atmosphere until the rate of production of oxygen began to exceed the availability of reducing materials. This point signifies a shift from a reducing atmosphere to an oxidizing atmosphere. O2 showed major variations until reaching a steady state of more than 15% by the end of the Precambrian. The following time span from 541 million years ago to the present day is the Phanerozoic eon, during the earliest period of which, the Cambrian, oxygen-requiring metazoan life forms began to appear.
The amount of oxygen in the atmosphere has fluctuated over the last 600 million years, reaching a peak of about 30% around 280 million years ago, significantly higher than today's 21%. Two main processes govern changes in the atmosphere: Plants use carbon dioxide from the atmosphere, releasing oxygen. Breakdown of pyrite and volcanic eruptions release sulfur into the atmosphere, which oxidizes and hence reduces the amount of oxygen in the atmosphere. However, volcanic eruptions also release carbon dioxide, which plants can convert to oxygen.[citation needed] The exact cause of the variation of the amount of oxygen in the atmosphere is not known. Periods with much oxygen in the atmosphere are associated with rapid development of animals. Today's atmosphere contains 21% oxygen, which is high enough for this rapid development of animals.
Currently, anthropogenic greenhouse gases are accumulating in the atmosphere, which is the main cause of global warming.[

Darwin, Dawkins, I mean, their names are so similar. There must be some conspiracy going on. Next, there'll be someone named Darkwings forcing down this anti-southern-baptist stuff. Yes, I said it. Evolution is really a whole campaign against the truth of the Southern Baptist church teachings. 'Nuff said.
(Just kiddin' of course.)

Thank you for answering the question.
We understand that Nitrogen came to earth by the heavy bombardment of Earth by huge asteroids.
Do you think it was due to chance and coincidence or it was guided and directed ?
The 2nd element is Oxygen which was produced by the photosynthesizing cyanobacteria, it happened that the bacteria convert the energy from the sun to Oxygen.
Do you think it was due to chance and coincidence or it was guided and directed ?
Please clarify on what you base your answer, is it on faith or on science & logic.

Fruit eating animals were first. But they were not exclusively fruit eating. They were plant eating. Over time the plants that were being eaten had developed juicier and better parts around their seed and the earliest forms of "fruit" began.

How in any way is it possible that humans could have been before air?
