Science would examine data and go where the facts lead them. Your data for god? You have a gut feeling that makes you feel food after your childhood indoctrination. An ancient holy book with thousands of errors and contradictions that has been rewritten hundreds of times. And last but not least, because you stamped your foot and said so.
Hmmmmm looks like a childish dead end if nothing.
That being established we will properly keep a wall of separation between church and state and govern society in a way of fairness, equality and justice for all.
Then, by all means, use the scientific method to disprove the existence of God. Minds far more brilliant than yours (which I have the utmost respect for) have failed to do so throughout history. All you can do is offer your opinion on the matter.
