The theory that our universe had a mindless physical cause perfectly predicts the universe we observe: a dispassionate, mechanical, mindless, physical cosmos. It makes complete sense of why we are made of frail matter, why life developed through a long and messy process of evolution, why the universe is so big and old, why we can never find any good evidence of supernatural beings or events, and so on. Since this is a plausible, comprehensible explanation for the universe, until we discover some evidence that challenges it, there is no need to resort to any alternative.
