Me versus God

How?
How can you do it?
How can you?
You who know the creation of new life as a chemical reaction you can draw,
You who can show every step of the way to build up the very substances of our flesh,
You who have seen the thoughts in our minds modelled as random interactions of simple systems on a computer still harbour such thoughts?
You who know the basis of our bodies, minds and souls to be as simple at their heart as an apple falling from a tree,
still find it necessary to believe in an explanation for the lights in the sky?
Does all of this mean nothing?
Can you discredit every original thought in the last thousand years as steps in the wrong direction and not know in your hearts you are making a mistake?
Why can't you remember that not everything your mother said was true? Why can't you believe that when you believe so much else?
WHY?
