Did the Pre-flood air have 50% more oxygen in it?

What do you think of this statement?

"Hyper-oxygenated air; the world was like a hyperbaric chamber, everything lived longer because of the air quality. We know this because we have air samples from before the flood; extracted from bubbles trapped in fossilized sap (amber). Adam lived until he was 930. Noah was 600 when he built the Ark"  

She is suggesting that we lived so much longer due to the heightened levels of oxygen available during the Pre-flood era.

Later it was said that this oxygen bound to hydrogen to create the oceans of water around us.

My best guess is that words and phrases had different meanings "back then".

We know that during the times of the dinosaurs the Earth's atmosphere had significantly more oxygen, but that in the millions of years that followed, this was not the case.

The evidence supports the idea that increased oxygen will help DNA based life forms grow larger.

  There is no evidence that it helps DNA life forms have a longer lifespan.

Unless of course someone is strangling you, and you smash them with a large rock.

Who would have ever thought that the phrase "Let's Go Brandon" has a completely different meaning?

The Oceans NEVER used atmospheric oxygen to form, hydrogen and oxygen, and many other gasses supersaturated magma and lava. The expansion as the pressure lessens is why a trillion tons of rock can be blasted 28 miles high, and circle the Earth.

The Oceans were originally saturated with water, methane, and iron, among many other things,  .... NO oxygen to speak of, until photosynthetic plant life in the water started creating oxygen, at which time the iron rusted, and fell out, and the methane escaped.

Whoever made the statements above this post is completely uninformed, and promoting an agenda driven scenario, completely false.
