Oh FFS. I just discovered that my wingnut sister actually believes the earth is only 6-10 thousand years old. Because the Bible says so, apparently. She's married to a doctor. On all that is holy, I hope he's better at science than she is.
Okay, my Christian friends, here's the problem, science isn't bullshit just because that'd be convenient for your world view. The Bible is a fabulous source of ideas for how to be a good person, but it kinda sucks as a science book. See, it doesn't mention giraffes at all, and last I checked, they exist. And it was written a LONG time ago. Before people understood anything about the speed of light (though apparently, some people still don't). And so the stories we told to make sense of the universe were like little children talking about how babies are made. They get bits right, but they miss a whole lot of the story.
Adam and Eve are stories. The 6 days story? A story. A tale we told to make sense of a world we didn't understand. And that's okay. We got the important part right: God made the universe. Or God is of the universe. Or the universe is of God. Or something. I dunno. :)
For a thousand years in your sight are like a day that has just gone by, or like a watch in the night. (Psalm 90:4, NIV)
