I believe the Bible. I also believe that, for example, “morning”, “evening”, and “day” don’t mean the same thing until the earth revolves around the sun and turns on its axis every 24 hours. There is such a time unit as a cosmic day, which is very long and might have been the first day. If it is lighter on one side of that turn than the other, there’s morning and evening. As to the origin of life, God invented it and made the creatures according to their kinds, one group per day. Is a kind a species? Not necessarily, but it must be specific enough to make some of them creeping things, some flying things, some mammals of varying sizes and habitats, etc. Well, that’s narrower than kingdoms and phyla. It seems to be narrower than classes. Perhaps God made classes, perhaps orders, perhaps even species. I also think the later mutations were controlled by God precisely, or they would be too improbable even given billions of years. With God directing them, it could have taken no time at all. I think many changes happened between the Fall and the Flood due to a very different climate and atmosphere and for spiritual reasons, but I don’t have to stick to that part.
As for Adam and Eve, I think they were made separately, and that Adam was made from earth. That is one way of explaining why the earth in various places calls people who have never been to those places. We are made of earth if you go back far enough, and the earth sifted around and settled in different places. Some spots are some people’s actual relatives. Of course, really we’re all related, but in some way God ties the earth to us individually as if to a sister even now. Doesn’t the Bible call earth our sister?
I can’t scientifically or morally believe in random or from-scratch evolution.
