No, it is not accurate to say that all creationists are unable to think about the Big Bang and evolution. Creationism is a belief system that posits a divine creator as the ultimate cause of the universe and life. While creationists may reject or interpret scientific explanations such as the Big Bang and evolution differently based on their religious beliefs, it does not necessarily mean they are unable to think about or consider these concepts.
There is a wide range of perspectives among creationists, and individuals may have varying levels of familiarity with scientific theories like the Big Bang and evolution. Some creationists may reject these theories outright, while others may seek to reconcile their religious beliefs with scientific concepts through frameworks such as theistic evolution or intelligent design.
It is important to recognize that people can hold different viewpoints and beliefs, and their ability to think about certain ideas can vary. However, it is not accurate to make a blanket statement that all creationists are incapable of thinking about the Big Bang and evolution.
