Evolution isn't a theory.
Correct. Evolution is fact.
But only within your religion/cult, or in the so-called theory of it.
Withing the whole scientific community and really most people. Statistics showed that the majority of the religious people, even your religion accepted evolution.
The Roman Catholic Church has long accepted or at least not objected to evolutionary theory. Pope Francis is not the first pontiff to publicly affirm that evolution is compatible with church teachings. In 1950, in the encyclical Humani Generis, Pope Pius XII said that Catholic teachings on creation could coexist with evolutionary theory. Pope John Paul II went a bit further in 1996, calling evolution more than a hypothesis.
Only a quarter of white American Catholics (26%) say that they do not believe in evolution of any kind and still dropping.
