    Hey
    I'm doing EPQ right now on how life evolved and whether it could arise on other planets - I found this book that talks about oxygen. The first chapter says "life must have evolved in an atmosphere that contained very little methane, hydrogen or ammonia" and then later on says "To summarise, life evolved in a primordial soup, with a planetary atmosphere containing methane, ammonia and hydrogen"
    I'm not sure which part to trust!? Is this guy completely contradicting himself, or should I just assume I'm misunderstanding what he's saying? Which view do you think is 'right' or at least closest to the truth?
    Thanks!

    Is the book not saying there must be some methane, ammonia, and hydrogen but not loads of it? You could mention in like a source analysis that the book is a bit unclear here.
