That is absolutely true to some degree—we want to find out what conditions support life, and why the Earth did end up how it did, and resulted in conditions stable enough and correct enough to allow life to evolve for millions of years essentially uninterrupted.
It's the tone that I read into, and I have a tendency to look out for the earth-centric perspective, mainly because I find the alternative way to look at it basically mind-blowing and fascinating. That doesn't make study of the development of our solar system any less important, any more than the study of evolution makes biology less important. The study of planetary formation, the solar system, geology and every other related field are all extremely important to broadening and deepening our understanding of how the universe works. Understanding statistics and the anthropic principle just gives us a framework in which to view that knowledge that is even more true and complete, in my opinion.
