this is your comment i was answering. from #2378
like i keep telling you both sides agree atmospheric conditions were different in the past and its not just a little bit of a difference
you some reason insist to inform me how different both sides view the past like i am not aware of that.
again fyi. you have great faith in proven fraudsters
let me add one more thing. helium in zircons and atmospheric c-14 are clocks that indicate a young earth. you wont consider it though will you?
Atmospheric conditions that existed way out of human lifetime. Not even known dinosaurs were alive that far back. You are comparing a hypothetical scenario that never took place.
Your brain was scrambling to justify a +900 year old human fairytale because you didn't want to concede the argument like a rational person. So instead you took out your trusty shovel and began digging a hole even deeper.
You saw 1 youtube video that mentioned oxygen therapy and thought to yourself wow I am a super smart christian scientist let me conclude with absolutely zero proof that increasing oxygen levels and make a gargantuan leap from it has some health benefits to "thats how people were able to live x10 longer". Then you googled "was there any time in history where oxygen was more readily available?". The search came back with yes but millions of years ago and your brain went yea close enough buddy.
Also oxygen levels do not dramatically increase lifespans. If that were true then people who live by the ocean as opposed to high altitudes where oxygen is much thinner would have much longer lifespans. They do not.
As a matter of fact it is the opposite people who live in altitudes of +10k-12k ft such as Swiss Alps, Himalayas, Andes Peru/Bolivia or Leadville Colorado enjoy lifespans 1‐3 years longer. Due to atmospheric pressure living in higher altitudes there is around 30‐40% less oxygen available per breath.
