The problem with going there is that it's easy to go to far, to a point where the Bible isn't true anymore and it's just your interpretation of bits and pieces of the Bible.

Yes, true. But it's possible to go too far the other way, too, which causes a lot of problems (see: the creationist movement in America).

I've never seen one instance of imprecise measurement, but if you know of one, fire away

2 Corinthians 4:2:

He also made a round tank of bronze, 7½ feet deep, 15 feet in diameter, and 45 feet in circumference.

I consider it more probable that the measurement is imprecise than that pi is three for that tank.

I mean, it's a minor detail, but it's there.

unmarked parables are also fairly easy to spot.

That's what I thought, too, but apparently some people take the Garden of Eden literally.
