The Christian ad is backed by faith and a belief that he does exist - so no scientific proof needed.
No other organisation could get away with outrageous advertising slogans like that for those reasons.
"Carlsberg. Definitely the greatest beer in the world."
"Slimfast guarantees you'll lose weight - no willpower required, just have faith."
What makes religion so special?
Also, note the atheist advert didn't say "there's no god" - therefore it's not shackled by faith in the same way religion is.
