Really, how do you decide?
I don't. I refuse to care anymore. Belief in God requires faith. So does belief in science. Unless I have the means to independently verify every claim ever made, on some level I have to put "faith" in the integrity and credibility and research of someone I've never met. I have to believe they are credible because people I've never met testify to the credibility of people they've never met. That doesn't cut it for me.
I also spent the best years of my life pursuing "God" and have nothing to show for it, not even an acknowledgement of my existence from him. Does he exist? I don't know. I don't care. If he wants to shoot the shit sometime my phone number is listed. Otherwise, I don't have time.
I do, however, have faith that Rocco will shred my last remaining livingroom curtain by the end of the day, and that I will soon be shopping for new ones.
