As always though richard, I cannot prove a negative. Make a claim then back it up, rather than ask someone to prove a negative

Asking someone to prove oxygen doesn't have a corossive effect ( as I said ) isn't asking to prove a negative.
That is the definition of proving a negative, I will try to speak your language!
Oxygen doesn't have a corrossive effect on humans, prove me wrong!

That's not proving a negative.
It is the definition of it, go on though darling. Illuminate me on the subject of oxygen corroding humans. Do you have any sources at all? Even the flimsiest ones?
The areas of chemistry and physics that deal with the characteristics and fundamentals of oxygen particles are deterministic the behavior of which can be proven. Its not a non-deterministic area where evidence or proof cannot be obtained as in proving a negative.
The only thing you're doing is showing you don't even know wtf proving a negative is.

corrosive oxygen?
Well the oxygen we breathe isn't corrosive to the respiratory system because, a.) the cells are still functioning to metabolise the oxygen, b.) the oxygen exists as O2 molecules.
The ones that are harmful to the cells are oxygen radicals, O. . Antioxidants in the body can take care of normal levels of oxygen radicals.
And as for dead bodies, oxygen is involved because the bacteria that are eating the cells need oxygen to thrive (most of them anyway). It's not a direct relationship between oxygen and corrosion.
As for why bacteria only destroy our cells when we die, it's because our immune shuts down, hence it is unable to kill the bacteria in the body.

Why does metal corrode and why is the process sometimes referred to as oxidation?
Free radicals being harmful (you got it wrong in referring to it as "oxygen radicals", btw) doesn't imply A) oxygen is a corrosive gas B) oxygen has a corrosive effect on a person's body.

Metals corroding is indeed oxidation, and it involves oxygen. Correct. But so you are trying to say that we are metals? There are complex systems in the body that prevent harmful levels of oxidation by oxygen molecules.
Okay fine. 'oxygen radicals' is not exactly a correct chemical term. Let's call them reactive oxygen species. Examples, oxygen ions and hydrogen peroxide.
Free radicals is a general term for many other molecules, not only those containing oxygen. That's why I tried to make it sound simple by saying oxygen radicals. i.e. free radicals which contain oxygen.
which is precisely the point.
Do you realise that I am trying to say that oxygen molecules, O2, are not corrosive to humans? That is why I backed up my argument by saying that reactive oxygen molecules are the ones that are harmful, not naturally occcuring oxygen.
Riddick do you have a masters degree in every single topic ever?
I don't know.
Are you going to strip naked and send me pics now, or are you here to take up space and breath all my precious air?
Have you ever wondered why the color of an apple beneath its skin changes colors?
What you're seeing is the corrosive effect oxygen has, it 'corrodes' the cells of the apple.
Oxygen has the same effect on the cells of a person's body.
Look it up, dear.
I don't know.

I know...
but...
Apple = humans. yes yes how believable.
If it has the same DEGREE of effect on our body, then...
Can you please explain why other fruits do not experience such degree of 'corrosion'?

Question: Why Do Cut Apples Pears Bananas and Potatoes Turn Brown?
Answer: Apples and other produce (e.g., pears, bananas, peaches, potatoes) contain an enzyme (called polyphenol oxidase or tyrosinase) that reacts with oxygen and iron-containing phenols that are also found in the apple. The oxidation reaction basically forms a sort of rust on the surface of the fruit. You see the browning when the fruit is cut or bruised because these actions damage the cells in the fruit, allowing oxygen in the air to react with the enzyme and other chemicals.The reaction can be slowed or prevented by inactivating the enzyme with heat (cooking), reducing the pH on the surface of the fruit (by adding lemon juice or another acid), reducing the amount of available oxygen (by putting cut fruit under water or vacuum packing it), or by adding certain preservative chemicals (like sulfur dioxide). On the other hand, using cutlery that has some corrosion (as is seen with lower quality steel knives) can increase the rate and amount of the browning by making more iron salts available for the reaction.

Well, yes. But different fruits have different degree of oxidation because they have varying amounts of these chemicals in the cells.
But humans do not really contain iron-containing phenols...
OKAY
strictly speaking, our red blood cells contain iron ions. The haemoglobin in these cells technically gets oxidated by oxygen to form oxyhaemoglobin. This is quite a similar process to apple browning, but do you even want to call this 'corrosion?'
It is true that oxygen is involved in our body in many oxidation processes. In fact, we depend on these oxidation processes to survive. Without them, the cells can't function.
But again, do you want to call this process corrosion?
I would say its: corrosion.
Only at a slower rate.
Only at a slower rate.
Though Riddick, most of these useful oxidation processes in our body are temporary. There are cycles to most of them. After they have served their function, they get reduced (unoxidized) back to the normal form.
We are talking about microprocesses here.

You're not saying it isn't corrosion. 
Corrosion undoubtedly has a micro process component also...

So you are saying every single oxidation process is corrosion?
Gaseous exchange in the body is corrosion? Enzymatic actions are corrosion? LIVING is corrosion?
What is your definition of corrosion?
When I said that they are microprocesses, I was intending to illustrate that they are not in a scale that is big enough for our naked eyes to notice any physical change. Not because I'm saying that corrosion has no mini-scale explanation to it. It obviously has.
