Compared to their body size Dino's have rather small nostrils. Hardly large enough to transport the oxygen necessary for an 80 foot long body weighing many tons
Except for the fact that it is large enough to transport the necessary oxygen.
So this leads one to believe that they either took one step and rested for 12 hours or, they needed to breathe less
Or the third option, you don't not what you are talking about because you are arguing from a position of ideological ignorance.
Because your beloved evolution would have evolved the necessary nose size for the creature to survive. Right? RIGHT?
First off there is nothing "beloved" about evolutionary theory, but unless you can come up with a better and more plausible theory then it will continue to stand. That's how science works. What evidence do you have to back up your original claim that dinosuars were not able to take in the required oxygen? None, other than a conclusion you can to based on a drawing. You have no legitimate argument to defeat.
Therefore the oxygen levels in the atmosphere must have been higher before the flood which in turn provided the necessary levels of oxygen requiring less breathing.
Oxygen levels were higher then, that is known and accepted science. However there is not a shred of evidence pointing to a worldwide flood.
So. How did we lose the oxygen levels?
Because atmospheric composition is not static and it can and does change over time.
The vapor canopy fell
A "vapor canopy" of even insignificant amount would both block out all sunlight and raise the pressure and tempature of the planet to the point where it would be sterilized. And that's not even counting in the gravitational energy the would be released by the collapse of such a canopy. It is simply not a plausible scenario by any means.
the "fountains of the deep" broke up at the continental fault lines when then released enough water from above and below to flood the earth.
Then why is there no evidence of such a thing occuring at any point in geological history. Either the internal heat or the potential energy released by such an occurence alone would turn that water into superheated steam that would poach everything on the planet, much less the two events combined. Further more where did the water go? there is not evidence of such an enormous amount of subterranean liquid water.
The result altered the atmosphere and left much more of the earth covered in water.
And by what mechanism would such a flood change the atmospheric composition? You can assert that it did until the cows come home, but the very fact that neither you, nor anyone else, has ever proposed a theory as to how or why those things happened, or even existed in the first place tells me that you are just making shit up. If an event of that magnitude happened, and especially in fairly recent geological time, then there would be incontrovertible evidence to be found that would support such a conclusion.
Noah's flood changed everything.
I highly doubt the story of Noah's flood changed anything besides giving young earthers an excuse for their abject and willful ignorance.
How about THAT
How about what? All you did was make a bunch of assertions, provided no proof for them, and then declared you were right just because you said so.
This has been another nose knows lesson for you from:
The All Seeing I
Yeah, sure. My nose knows horse shit when I smell it, and you reek of it.
