There are other explanations for "fine-tuning" than God.
This is very true. One explanation is that Unverses (Universi?) pop into existence all the time and each one has different physical constants determined strictly by chance. It just so happens that this universe ended up with physical constants benefitial for the creation of life. No Guiding Hand was involved, just chance.
But I like the idea of the Guiding Hand better.
