Simplest with least assumption = best answer?
I am an Agnostic so I am not sure.
The idea of a god is fraught with issues, including exactly what is meant when you say 'god'. If there is a god, I doubt it is a personal entity, more likely a force inherent in nature with no personality. I do have panthestic tendencies...ha.
If there is no god then the serious questions of how, and why come up. How did clay became man, it appears to be a long and involved story with a lot of almost unbelievable amount of luck involved...but obiviously over a tremendous period of time.
And why...how does existence make sense?
God can not answer nothing cogently yet is posited as a cause for everything. Evolution is limited in it's application and can actually answer things with evidence.
