Skepticism is a healthy part of life and critical thinking, no one should just blindly accept everything they hear. But taking this to the naturalistic extreme of saying one should only believe that which is 100% certain and beyond question - and thus reject God for not being "provable" - is simply an unrealistic and untenable way to live life. A healthier approach as a Christian is to follow St. Anslem's advice of "faith seeking understanding", choosing to seek out answers to our doubts and questions because we have faith in God.
