Does it matter? I suppose it depends on a person's individual viewpoints. If you believe in God and care about what he wishes you to do or you have a "fear of his wrath," then it would matter. If you do not believe in God and don't care, then I suppose it would not matter.
Those who believe in a God would respect the fact that he gave us free will. Those that do not believe in God respect that most life forms, above all humans, have free will.
I suppose it depends on where your priorities are focused.
I yearn to understand, but unless I see signs from the heavens, I may never completely grasp the meaning to life, but that does not mean I will ever stop looking. I personally believe in God. Perhaps not the Hebrew genocidal God or the fat Buddha God or the other Gods people in history have "adopted" and "imagined," but I do believe in a God. And, if there is a God that created me and created life, then I want to please him. Unfortunately, God can not be proven or disprove at this point in time.
What really matters is what is important to you and what feels right in your heart as an individual.
