Thinking and Observing

So is it fair to say that those who become atheist after pondering and “Deep Thinking” are the ones who direct their thoughts and observation in the wrong direction from the beginning without even considering the possibility of existence of the Almighty Allah:subhanahu: even for a moment?

Even if they were muslims at one point in their lives, they did not accept the religion with a sincere heart and with the honest intention and hope from Allah :subhanahu: to be guided in the right path and direction???
