Hi, I see it in the following way. Religion bases its postulates on faith and science on facts. So it is true that if you destroy all science, it will always resurface in the future, which if it is not certain is whether it is the same, whether gravity exists or not. Religion depends on who initiates it and how to guide its followers and give them faith and hope.
The interesting thing is that all people have religion (by the complete definition of religion). And in their religion, all of them use science, even if it is only some crude form of engineering - like the wheel.
The practical, in-practice, divisions between science and religion fade away as these two things blend together in the lives of all people.
