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.
"If we threw a handful on an island and they raised themselves I think they would believe in God."
Children are born believers in God, academic claims
"Children's normally and naturally developing minds make them prone to believe in divine creation and intelligent design. In contrast, evolution is unnatural for human minds; relatively difficult to believe."

Humans are naturally predisposed to believe in gods and life after death, according to a major three-year international study.
Led by two academics at Oxford University, the £1.9 million study found that human thought processes were “rooted” to
religious concepts.
But people living in cities in highly developed countries were less likely to hold religious beliefs than those living a more rural way of life, the researchers found. The project involved 57 academics in 20 countries around the world, and spanned disciplines including anthropology, psychology, and philosophy.
Children were asked whether their mother would know the contents of a closed box. Three-year-olds believed that their mother and God would always know the contents, but by the age of four, children start to understand that their mothers were not omniscient.
