I’ve been trying to come up with what I’d say to the OP’s friend. I am a Biblical literalist. If you put a gun to my head and made me pick evolution or young-Earth creationism, I’d go with the latter. Which is not to say that I think they’re right. Still, I have a major problem just putting aside the six day thing myself.
However, I’ve increasingly come to two conclusions, presented as questions:
**1) Does it really matter? **
It’s not like Genesis Chapter 1 is a guide I can use for my daily behavior, and it’s not the kind of thing that would affect salvation in any way.
**2) How arrogant are we to believe that we’d know the answer? **
To elaborate on the second point, let’s think about the major church vs science debate in Galileo’s time. Galileo argued that the Sun was the center of the universe, when the common church view said that the Earth was the center. There wasn’t a lot of Biblical support for the geocentric view, but there were plenty of church-folk who insisted on it as a point of doctrine. And yet… it turns out that the heliocentric view of the universe was wrong too. The sun is only the center of the solar system… not the galaxy and not the universe. Furthermore, we came to our senses and realized that the Bible didn’t really care what was at the center of the universe.
I can’t help but think we’re in the same position here. The traditional Sunday School version of creation isn’t even 100% consistent with Genesis. (In Genesis 2, Adam is created before plants are on the earth. Then Adam has a chance to name the animals before Eve is created. Yet Gen 1 says that plants were created, then animals, then “male and female he created them.”) In fact, the more I look at Gen 1 and 2 together, the more I think that the Garden of Eden was a completely separate act of micro-creation done at a separate time from from general creation. Maybe not.
But maybe the Genesis account is something like what we see in Revelations. It could be both literal and true… as seen from heaven through a spiritual perspective. Or maybe it is purely poetry and not even a version of historical truth. I don’t like that explanation. In fact, I hate it. But it would be a little cocky for me to assume that I, or my pastor, or even my denomination, are in possession of the one single correct interpretation of the Bible.
As for the scientific position: our current understanding of the universe doesn’t account for 23% of the mass and 72% of the energy. Surely any theory based on the 5% we can see is going to undergo major revisions in the years to come. Just ten years ago, it was assumed that the universe’s expansion was slowing or reversing, but we’ve now established just the opposite. Science still can’t decide whether life came from deep-sea vents or intertidal pools (or even from space itself). I’m not necessarily taking the stance that YEC’s push (that there is some kind of fundamental error that will totally overturn science as we know it), but no honest scientist is going to say that we’ve seen more than the tip of the iceberg.
Something else for the OP: Have your friend read the book of Job. In case he’s not familiar with what’s really happening there, Job is a debate between five people (Job, his wife and three others) about how suffering can exist in the world and what it really means. They use logic, scripture, conventional wisdom and more. Each of them is pretty much convinced he’s correct. At the end of it all (chapter 38), God steps in: "1 Then the LORD answered Job out of the storm. He said: 2 ‘Who is this that darkens my counsel with words without knowledge?’ " Ironically, God is taking Job’s side: "After the LORD had said these things to Job, he said to Eliphaz the Temanite, “I am angry with you and your two friends, because you have not spoken of me what is right, as my servant Job has.” (Job 42:7)
So… there’s just no way for a believer to win by taking a dogmatic approach on these kinds of things.
