If there is no God, there is nothing to change and no direction to change it in.
On the contrary. The laws of nature allow for change from the big bang to where we are today. From primitive man, archaic laws to scientific discoveries we live in a world of continual change.
With god you are indoctrinated to believe in answers that you are not allowed to question. You are blinded by God's divine plan which he has concocted since time immemorial which if he has already planned, you have no control over. So in that since with God there is no change. Life is in god's hands not ours.
No God implies apathy and hopelessness. Fortunately, many atheists are too irrational to actually live that way...
No god implies man goes out and find the answers to the universe. Question our existence and develop laws for the good of humanity.
God implies stagnation in 1st or 6th century desert doctrines that are not allowed to change because god says so. Ideologies that are tribal centric and barbaric.
Advancements both humane and technological over the past 300 years has mainly come about because of man's freedom from the shackles of religion. Religions that subdued the spirit of human knowledge and growth with the use of killings and torture.
