Atheism can send the wrong message across to people, especially those weaker in faith but brushed off and laughed at by every religious sect out there. It is not a religion, just a group of non believers.
Yes you are right. People should realize that Atheism comes from a lack of knowledge and information and misinterpretation of their understanding of what is and what is not.
But, common knowledge and logical explanations can often decide the battle between a religious sect and an Atheist group.
It is highly ridiculous to disregard the fact that God does not exist when we have some common sense.
You are right. God exists very where. Proof is around us, the mere existence of us humans is one logical reason of believing a creation is created by a creator. Only people without knowledge turns Atheist.
