Ricky Gervais explains why he takes a pass at the whole god idea and why science is the better place to put brain power (breaks and bold added).
Science seeks the truth. And it does not discriminate. For better or worse it finds things out. Science is humble. It knows what it knows and it knows what it doesn’t know. It bases its conclusions and beliefs on hard evidence—evidence that is constantly updated and upgraded. It doesn’t get offended when new facts come along. It embraces the body of knowledge. It doesn’t hold on to medieval practices because they are tradition. If it did, you wouldn’t get a shot of penicillin, you’d pop a leach down your trousers and pray. Whatever you “believe,” this is not as effective as medicine. Again you can say, “It works for me,” but so do placebos.
My point being, I’m saying God doesn’t exist. I’m not saying faith doesn’t exist. I know faith exists. I see it all the time. But believing in something doesn’t make it true. Hoping that something is true doesn’t make it true. The existence of God is not subjective. He either exists or he doesn’t. It’s not a matter of opinion. You can have your own opinions. But you can’t have your own facts.
