It is disbelief of God in its very nature. It tries to say that God had nothing to do with the existence of humanity. It is disbelief in God and a direct contradiction of God's word.
That is exactly what evolution is. It's based off of naturalism which tries to eliminate the possibility of divine intervention in any human affair. It is the epitome of man's rebellion against God
Pope Francis says the theories of evolution and the Big Bang are real and God is not “a magician with a magic wand” putting an end to the “pseudo theories” of creationism and intelligent design! So the Catholic Church, Church of England and mainstream churches all accept the big bang and evolution!
Lord Carey the former Archbishop of Canterbury put it rather well – “Creationism is the fruit of a fundamentalist approach to scripture, ignoring scholarship and critical learning, and confusing different understandings of truth”!
No. The direct statement is best. Your way implies the questionable assumption, "if evolution then not god." Something unproven. (Unless your assertions require me to prove you wrong.)
