No, you're not very committed if you think his smartass mockery of Christians is funny.
The pretense of atheists demanding "proof" is specious, fatuous, disingenuous and ignorant.
1. Science doesn't do proofs.
2. "Nothing is known for certain except in pure mathematics." - Carl Sagan
3. Scores of books have been written providing a dearth of convincing evidence of Nature's God, named in our Declaration of Independence.
4. "In God We Trust" is America's motto. Deal with it, godless Leftists.
The New Evidence that Demands a Verdict by Josh McDowell is the finest book I have read providing 900+ pages of thoroughly documented evidence these charlatans pretend to seek and want. I took copious notes of it and can forward them to anyone of good will.
