Cuz nobody can ever win a debate on religion. Atheist claim that religious peoples' stories aren't true, but they can't prove that. And then the religious people insist on their story, and they can't prove it right either. lolol i'd say it's stupid to get in a fight about religion
Well, first of all, the burden of proof is on those who claim the existense of a diety, not on atheists, who reject those unsupported claims.
Second, actually, science has already disproved some bullshit, such as 'flood', 'creation', 'young Earth', 'Sun circling around Earth' and so on.
