Challenge: There Would Be More Life if the Universe Were Fine-Tuned for Life

Today’s challenge is from a comment we received on the blog:

You've got the fine tuning thing wrong. The universe is not fine tuned for life. Your God is an incompetent designer if it takes that volume of universe to create this insignificant volume of life. Seriously, life is so rare in the Universe it's astonishing.

This isn’t just a scientific question, it’s also a theological one, so I’m interested to see the range of your responses—leave them in the comments below! Brett’s video response will be posted on Thursday. (If you’d like to see some hints as to how I’d go about answering this one, see here and here.)
