There is evidence to support that some aspects of creationism are a result of how our thinking processes evolved.
eg. an article on this by a lecturer in developmental psychology
"Developmental psychologists have identified two cognitive biases in very young children that help to explain the popularity of intelligent design. The first is a belief that species are defined by an internal quality that cannot be changed (psychological essentialism). The second is that all things are designed for a purpose (promiscuous teleology). These biases interact with cultural beliefs such as religion but are just as prevalent in children raised in secular societies. Importantly, these beliefs become increasingly entrenched, making formal scientific instruction more and more difficult as children get older."
We're wired to try and make sense of our environment within a comfortable frame of reference and we automatically look for ways to interpret data based upon prior experience. Exceptionally useful a lot of the time, bit of a hindrance at others.
