i don't know where does oxygen came from,
i never claimed i do.
Instead i quoted you scientists who made the experiment who both admit that assumption about oxygen is pure speculation.
It is not a fact and there is absolutely no theory which can explain this,
Miller and Urey stated these things
because without Oxygen there is no Ozone and without ozone UV radiation decomposes ammonia - ammonia cannot exist without ozone.

buddy,
that "truth" on that site is speculation
- there is no experiment confirming that.
and your link states

If all the nitrogen in the contemporary atmosphere had existed in the form of ammonia in the early atmosphere it would have been degraded by ultraviolet light in 30,000 years [later revised by J.P. Ferris and D.E. Nicodem to 100,000 - 1,000,000 years]. If the ammonia surface mixing ratio were on the order of 100,000 as Sagan has estimated, then the atmospheric lifetime of ammonia would have been a mere 10 years. It would also have been difficult to maintain substantial levels of hydrogen sulfide in the atmosphere. Hydrogen sulfide would have been photolyzed to free sulfur and hydrogen in no more than 10,000 years. The concentration of hydrogen sulfide in the ocean would have been further attenuated by the formation of metal sulfides with their notoriously low solubilities. The same photodissociation process would have applied to water to yield hydrogen and oxygen.
Not that it is only pure speculation without any scientifical proven basis, they quote research of Carl Sagan who personally stated this

You will say that about anything which attempts to show the status of Early Earth, barring the use of some time machine. And even then, you'd probably suggest that the time machine wasn't taking us back to the proper time LINE.

Such experiments can be done and from what i heard similar actually were done and it turned out that in such concentrations living organisms could survive in time in order of magnitude of hours.
Thats extremely short timescale for "evolution"

And for you to talk about SPECULATION when you support a mysterious magical big daddy in the sky is the epitome of projection.
you are putting words in my mouth which i never said to discredit me.
So you reject both Creationism and Evolution both, eh? Uh-huh...

You didn't answer my question. You didn't explain your theory as to where this destructive Oxygen came from.
Hello there Aeon, this fits in nicely with the scientific facts of Creation:
5 — THE PRIMITIVE ATMOSPHERE
ATMOSPHERE WITHOUT OXYGEN—Could a non-oxygen atmosphere ever have existed on Planet Earth? It surely seems like an impossibility, yet evolutionary theorists have decided that the primitive environment had to have a "reducing atmosphere," that is, one without any oxygen. Now, the theorists do not really want such a situation, but they know that it would be totally impossible for the chemical compounds needed for life to be produced outside in the open air. If oxygen was present, amino acids, etc., could not have been formed. So, in desperation, they have decided that at some earlier time in earth's history, there was no oxygen in the air! And then later it got it somehow!

But there is a special reason why they would prefer to avoid a reducing atmosphere: There is no evidence anywhere in nature that our planet ever had a non-oxygen atmosphere! And there is no theory that can explain how it could earlier have had a reducing atmosphere—which later transformed itself into an oxidizing one! As *Urey himself admitted, a non-oxygen atmosphere is just an assumption—a flight of imagination—in an effort to accommodate the theory.
"This problem practically disappears if Oparin's assumptions in regard to the early reducing character of the atmosphere are adopted."—*Harold Urey, "On the Early Chemical History of the Earth and the Origin of Life, " in Proceedings of the National Academy of Science, 38 (1952), p. 352.
Oxygen came from the plants that were present when the earth was formed,
3) That the Earth had a 12"' canopy of dense water that
blocked out all the harmful radiation, provided a constant high pressure system, which gave 35% oxygen and humidity that allowed for ALL things to grow to giagantic size.
There is no evidence anywhere in nature that our planet ever had a non-oxygen atmosphere!
There is no evidence which you will accept. I already explained this to you once. We know where oxygen comes from -- it comes from plants and some micro-organisms. Without those LIVING things, there would be nothing to replenish Oxygen, even if it were present. So let's pretend that there was some Oxygen, but nothing to replace it as it was used-up. You're still left with the same problem once the Oxygen is used-up.
