Evolution doesn’t explain an orderly universe with suitable physical laws, A fine-tuned universe, including initial conditions and physical parameters necessary for carbon-based life, a suitable planet, such as Earth, orbiting a suitable star and capable of supporting life and the existence of life in the first place. It also doesn’t explain the self-awareness of man and how one creature seems to have domain over this planet.
Believing in something that exists outside of time and space isn’t really as unreasonable as it sounds.
Theism is more about the why, science is more about the how.
