Why Is Evolution Defended?

Since the day of its formulation, the evolutionary theory has served the best interest of so called materialist philosophy.
We find it is these as well as others who work hard day and night to keep this theory alive.
It is now evident in schools, zoos, libraries, TV, just about in every corner and every aspect of our lives.
Why is it so much defended? despite the obvious floors in its theory. Michael Walker Quadrant, October 1982,p.44  answers this question "One is forced to conclude that many scientists and technologists pay lip service to Darwinian theory only because it supposedly excludes a creator"

So the only purpose of the theory of  Darwin is to keep and promote materialism, which denies God.
The only purpose of religious people like me is to refute this claim and promote the truth which is in God.
