Religious teachings tend to be far less moral than the morals most people use in their everyday lives. The Bible promotes genocide, rape, slavery - including sex slavery, severe prohibitions against thought crimes, infinite torture, etc.
Humans have an ability, independent from the various religious teachings, to determine right from wrong. Some people do it better than others, but most people do it better than the writers of the religious teachings. That's how most people determine that the Bible is wrong on these issues.
On average, world-wide, countries and regions with more atheists have less crime and higher living standards. I'm not necessarily saying they are directly related, but it sure goes against any claim that morality comes from a higher being.
