Bro. Alford's talk "The Wonders of Creation" at Cedar Point assembly September 1919, according to the Sandusky Register:
[Talking about the Flood]
" A whole earth full of exuberant life was destroyed, both animal and vegetable, also millions, doubtless, of the human race. This is evidenced by the present atmosphere surrounding the earth. Scientists tell us that 77% of the atmosphere is nitrogen, an inert gas which undergoes no change when it is breathed by animal and plant life. This, we are informed by those who have made it a study, is a gas composed of organic substances decomposed and changed to gaseous form, in other words, the element called nitrogen is the direct result of decomposition of organic matter at the time of the flood." [italics mine]
[Gross, I'm breathing dead people...] WAIT THERE'S MORE.....
"The wonderful economy of God is evidenced by the fact that when the resurrection takes place, and “all those that are in their graves shall come forth” by the end of the thousand years of the Millenuim, all the nitrogen will have been used from the air for the creation of the 20 billions of human bodies, and for the enriching of the soil of the earth, so that the restored human race will find the atmosphere composed of oxygen and carbon dioxide, the oxygen for the human race and the animals and the carbon dioxide for the plant life."
So yeah, I guess we're all gonna breathe pure oxygen in the new system....
