the science teacher that should be a religion teacher

The past week or so in my earth science class we've been talking about the age of the earth,fossils, carbon dating and other things of that nature. The teacher is a really religious guy and so we were talking about genesis 1 and the days of creation. He was talking about the views held by different christians. Some believe they were a literal seven days, others believe they were a thousand or so years and others believe other really strange things. Personally I've never really liked the fact that there's some questions that the Bible doesn't answer ie. the age of the earth and how long the 7 days really were. And I'm sure that I can't be the only one that gets frustrated by not understanding everything. But he said something along the lines of "I really hope we don't understand everything in the Bible because it was inspired by God and we don't want a God that can fit inside our tiny minds." That statement made me think that now it makes sense why I don't understand every little analogy and detail in the Bible. He also pointed out that knowing things like the age of the earth don't really matter in the scheme of the religion. So I thought that was cool cause he's really good a making connections between religion and science.
He also made another observation about the days of creation.
Day 1: light and darkness
Day 2: sea and sky
Day 3: land and vegetation
Day 4: sun, moon, stars
Day 5: sea animals and flying creatures
Day 6: land animals and people
here's the observation. He made light and dark on day 1 so that the sun, moon, and stars could be seen on day 4. He made the sea and sky on day 2 for the sea and flying animals on day 5. And He made the land and vegetation on day 3 for the land animals and people on day 6. I didn't really word that as elequently as my teacher did but that's the gist of it.
