It's not logic to not believe in god just because your parents couldn't answer your questions about god. Whatever the nature of God they believe in, you must look for the truth about god with yourself and to know deeply about different religions in this life. For me, I'm not atheist, and I believe in God, to be more specific; I'm Muslim and I believe in Allah as the lord and the only God of this World. Why I believe in God?! because God always says to us "I'm here". Where do you think the idea of an existent God came from? Besides that there are many many evidences that prove the existence of God, as you are atheist, Don't you think that its really weird if thousand of prophets and messengers had appeared in different nations and in different ages and all of them claimed that they are sent to people by GOD, and all of them had carried the same message and the same concepts ? !!! Anyway, There are two probabilities that brief this issue; 1- If the God is a reality and I believe in him and you don't, so you lose. 2- but if the God is not real, so nobody lose. .... In both cases, I'm on the safest side as a believer, but you are making some risk by not believing in God. Give it a try and learn about Islam http://www.islam-guide.com/
