The Designer Universe

Do we live in a "designer universe"? The laws of nature seemed fine-tuned for conscious life to emerge; if the fundamental constants of physics are off by only a hair, the universe would have been a lifeless dud (no stars, no stable elements, etc...) This reminds me of one of Thomas Aquinas' 5 Ways (order in the universe implies an intelligent creator that we call God), and the finely tuned universe seems to support some sort of Cosmic Designer. However, the Cosmic Designer Hypothesis is only one way of explaining the improbable fine-tuning of natures laws (and it is flawed to begin with). Theres the "Big Fluke Hypothesis", which doesn't provide much of an explaination, and then there is the "Many Universes Hypothesis", which claims that there are, suprise, many universes (perhaps an infinite amount), the idea being that we live in the lucky one universe where everything came together. All the theories have their own advantages and disadvantages, and its quite fun to ponder why our world is the way it is...
