Dr Justin Barrett, a senior researcher at the University of Oxford's Centre for Anthropology and Mind, claims that young people have a predisposition to believe in a supreme being because they assume that everything in the world was created with a purpose.
He says that young children have faith even when they have not been taught about it by family or at school, and argues that even those raised alone on a desert island would come to believe in God.
"The preponderance of scientific evidence for the past 10 years or so has shown that a lot more seems to be built into the natural development of children's minds than we once thought, including a predisposition to see the natural world as designed and purposeful and that some kind of intelligent being is behind that purpose," he told BBC Radio 4's Today programme.
