All of those ideas and those unlisted are encompassed under a single term: abiogenesis – which is the idea that life can spontaneously manifest out of non-living components. You might also hear the termbiopoiesis tossed about in this conversation, which is just a more specific reference to the three stages of the development of life. But these fancy scientific words are such a small part of the question, it’s unfortunate so many people get hung up on them.

What he says is basic Biology. Everybody knows that green plants feed on Carbon Dioxide and produce Oxygen as a by-product for us humans to breathe.
