(Disclaimer: This transcript is auto-generated and may contain mistakes.) I recently published a video called the canopy theory exposed and many people had questions about well if the canopy theory is not true how do people live so long in the past how they live to be over 900 years old and how did animals get so big like what we find in the fossil record. Well I cover this in my book truth and genesis exposing the lie of evolution in millions of years and I'll touch on it briefly here in this video. Here's an article from back way back in 1993 it says new theory lack of oxygen not asteroid killed the dinosaurs and they say an 80-foot long apatosaurus had a set of nostrils about the same size as a horse's nostrils they went on to say that there were some serious problems with trying to get air into that animal they said dinosaurs could not have existed without having more oxygen in the air to start with and interestingly science has proved that there was much more oxygen in the past than what we have today and they've done this by looking at amber bubbles amber is petrified tree sap sometimes air gets trapped in the tree sap before it is hardened and an air bubble is preserved in the amber and research has shown that some of these air bubbles in the amber have 50% more oxygen in them than we do in our atmosphere today our atmosphere has 21% oxygen and the research has shown that there's in the past was over 50% more oxygen says right here analysis of the gases in these bubbles show that the Earth's atmosphere contained nearly 35% oxygen compared to present levels of 21% oxygen so there is much more oxygen in the past than what we have today at least 50% more and with much more oxygen in the past this could have contributed to people living much longer before the flood the Bible says the people before the flood lived to be over 900 years old Adam the first man lived to be nine hundred and thirty years old Noah was nine hundred and fifty years old immediately after the flood lifespans dropped off to just over 400 years old and then as time went on the lifespan dropped off to just over 200 years old and then Abraham lived to be just 175 years old and now today it's very rare for someone to live to be over 100 years old greater oxygen in the atmosphere could have contributed to people living longer in the past and it also could have contributed to animals growing much bigger than what they do today here's a fossilized millipede that was found that was over six feet long and one and a half feet wide a fossilized dragonfly was found the size of a seagull fossilized oyster shells have been found on top of mountains and they were huge here's a man sitting on one now how do you get giant fossilized oyster shells on top of mountains well obviously there was a worldwide flood a fossilized rodent over 1,500 pounds has been found now that's a big guinea pig a rodent the size of a buffalo researchers say they have found fossils for a 1,545 pound giant that thrived in the past in a swampy South American forest here's a giant fossilized hurdle that lived in the past it was measured at over 13 feet long and 16 feet wide flipper to flipper so obviously the world before the flood was very different there was much more oxygen in the atmosphere and this probably allowed people to live longer and it obviously allowed animals to grow much bigger than what they do today now a simple fact of science is that reptiles never stopped growing they grow all of their lives so what would happen to a reptile if you put him in the pre-flood world and let him live to be over 900 years old well you'd have a pretty big lizard on your hands dinosaurs would have thrived in the pre-flood world for more information be sure to check out my book truth in Genesis exposing the lie of evolution in millions of years you can get it on amazon.com or just click the link below it'll take you straight to it so let me know what you think about this video in the comments below and if you haven't already be sure to hit the subscribe button and stay tuned for more videos thanks for watching
