Doctors Without Borders is a non-religious (mostly atheist) organization.
Bill Gates, George Soros, Warren Buffet and Richard Branson are all atheists who give many billions of dollars to saving lives around the world. 
At 69 I do way more charitable work as an atheist than I ever did as an evangelical for 46 years. If you want to start some kind of "who's more charitable" war as proof of your religion's validity, then go ahead. But it's pretty pointless.
