Well, almost everything you've said is absolutely false.
Evolution and creationism are assumptions used in science to get interpretations.
This is false. Evolution is the scientific theory that explains the diversity and history of life on Earth by the processes of natural selection and random mutation. It is a conclusion from evidence, not an assumption.
Creationism is a modern religious movement associated with conservative, Evangelical Christianity that promulgates falsehoods. When evidence is shown to creationists that contradicts the Bible, they ignore or attack it.
Evolutionists assumption is that there is no God
This couldn't be more false. Evolution is not a theological position; it makes no assumptions about the existence of God. Rather, it's a scientific model that explains the history and diversity of life, and how all living things are related by common ancestry.
I mean, what you're saying is ridiculous. The majority of American churches, as well as the Catholic church, reject creationism and accept the scientific consensus of evolution. Are you saying that none of those churches believe in God? That the Pope is an atheist? That's nonsense.
Creationists - world wide catastrophe -> *look in bible* -> Noah's flood
The problem is that these creationist "explanations" don't actually explain the
pattern of fossils as we find them.
The evolutionary model
does, which is why it's accepted by the consensus of scientists and creationism is not.
Many people misunderstand science, evolution, and creationism.
Just you, looks like.
