Questions about "oxygen"?

Question

How was oxygen created from the big bang?

And what does the oxygen do to the living creatures?

Why the oxygen is important element to the living creatures?

Answer 1

it is impossible to answer the first question since at the big bang there was at lest the first thousand years no atoms.

Many animals need oxygen for their need in energy. But for some bacteria oxygen is a poison

Oxygen is important to animals since the nervous cells die quickly without oxygen

Answer 2

The big bang did not create oxygen...the element existed prior to that. We have about 100 elements (more if you include some of the creations of radioactive elements that are unstable) and they were all present at the time. Oxygen does the same for life as it does for fire...it supports combustion. Which is to say that it aids in the burning of food to provide energy but in man and other complex animals, oxygen allows a complicated anatomy of various organs and blood circulates the oxygen to keep all of those cells alive. In simpler life forms, the oxygen is absorbed into the cells themselves. Plants have rather a double life as both users of oxygen and producers of oxygen when during the day, sunlight breaks down carbon dioxide into usable material to create sugars and releases oxygen and at night, use oxygen to continue the process. Oxygen is important to many living creatures but not all, some bacteria are anerobic (living without oxygen). Oxygen also is harmful in high concentrations as it burns out body tissue. Divers use compressed air...not oxygen as pure oxygen would be lethal.

Answer 3

Good question. I think that as thought wakes up to the widely accepted theories of how and why, it finds big (huge) holes in these theories. It does not make sense that "intelligent" life would determine from the outset that it would like to be contingent upon other substances and at the mercy of substance, so to speak. Oxygen is one of three contingencies that "life" hangs on. How seeming living cells are happy to keep on keepin' on when they get oxygen or make a decision that they just can't go on without it is a permanently debatable question. Unanswered questions lead belief to new places.

Answer 4

The Big Bang created only Hydrogen and Helium (I'm afraid Frank is out of his mind, he states that there was Oxygen BEFORE the Big Bang, but right after the Big Bang, elements did not yet exist!)

This Hydrogen and Helium later contracted into stars.

Nuclear processes in stars created elements. For example:
- fusion of H2 (deuterium) and H1 (hydrogen) given H3 (light Helium)
- fusion of two H3 atoms gives an H4 atom (regular Helium) plus two hydrogens
- fusion of a H3 and a H4 gives Be7 (Beryllium)
- Be7 plus an electron gives Li7 (Lithium)
- Be7 + H1 gives B8 (Boron )

- Be8 and He4 gives C12 (Carbon, which is key for life)
- C12 and He4 gives O16 (Oxygen, also key for life)
- O16 and He4 gives Ne20 (Neon)
- Ne20 and He4 gives Mg24 (Magnesium)

- C12 and C12 gives Na23 (Sodium) plus H1

- O16 and O16 gives S32 (Sulfur)

and so on


and more elements are formed as neutrons from ongoing fusion processes hit existing atoms.

so that's how Oxygen was formed: in the core of stars, by nuclear processes

I'm afraid this is too long already so I'll leave the 2nd bit of your question for later?
