Hello, the earth did not have or never had Hyperbaric Chambers for any of its people this is because hyperbaric chambers are man-made ideas for movies. If you will notice the Bible says that the Ark was used to save Noah and His family, not chamber built on the ark in which they slept through the flood. I will remind you that the Bible stories are not real and there was never a flood, or a man named Moses, the stories of the Bible are made up.
