When all potential possible outcomes are considered, both our universe and Earth are way too perfect for life.  Life would not exist if gravity, nuclear and electromagnetic forces, the size and luminosity of the Sun, the distance Earth is from the Sun, the Earth’s speed of rotation and nearly perfect circular orbit, just right gravitational lunar pull for moderate tides, the existence and placement of so many ores near the Earth’s surface, the amount of radioactive heat generated in the Earth’s core for creating a protective magnetic field but not too much volcanic activity, etc.... were different in the slightest.  A basic principle of scientific analysis is that when one observes highly structured order where you would expect disorder, one can infers an intelligent creator.  This specialization of Earth is impossibly unique even when taking into consideration that there are billions of galaxies with a billion stars each.
