Notice how much time, focus and intelligence you need to create a stupid program full of bugs... how can this complex universe programmed with intelligence and impressive accuracy be formed without a creator (God)?
You as a programmer, it is not reasonable to be an atheist at all sir.
I am proud to be a Muslim, and I thank God that I was born a Muslim and did not get tired to find it. I know that as a programmer you read a lot, so it will not harm you if you read a little about the Creator of this universe. You will not regret and you will find the peace that you did not dream of on this earth.
