I'm not a creationist, but I think this is probably the case for this galaxy.
For example, it has been demonstrated that Earth has the right-sized moon to allow life to develop. Life takes a long time to develop. If the moon were smaller (or wasn't there at all), Earth would have an unstable axis: polar regions would change every 100,000 years or so and life wouldn't have a stable environment in which to develop. If the moon were bigger, we'd have an unstable double-planet system. Combined with our relatively quiet location in the galaxy, our abundance of water, our moderate size, our atmosphere and our distance from the sun, I think we have a unique place in the galaxy.
Yes, I’ve read some of those theories about the moon being a guardian angel for life. It is another reason why I think life may be isolated to earth. The events that allowed the earth to have such a large moon may be very very rare.
