It doesn't explain anything. If I could get past gravity, I'd tell them how we reproduce, how long we've been here, apparently, and a little bit about evolution. I didn't learn until I was in college about all the other cultures, and I should have learned that in the first grade. Cultural relativity is defensible and attractive. It's also a source of hope.
