Sir David Attenborough has campaigned against schools in Britain teaching creationism, believing students should learn about science in schools and religious teachings should be kept in religious institutions. He is a firm believer in evolution and how it could be used to explain the diversity of life on Earth, using the evidence from around the world as back up for his statements.

He also illustrated his points and view in an interview done on BBC with Mark Lawson.

In numerous interviews, he has always used the story of the parasitic worm in Africa to explain why he is not fully convinced by religious faith.

“My response is that when Creationists talk about God creating every individual species as a separate act, they always instance hummingbirds, or orchids, sunflowers and beautiful things. But I tend to think instead of a parasitic worm that is boring through the eye of a boy sitting on the bank of a river in West Africa, [a worm] that’s going to make him blind. And [I ask them], ‘Are you telling me that the God you believe in, who you also say is an all-merciful God, who cares for each one of us individually, are you saying that God created this worm that can live in no other way than in an innocent child’s eyeball? Because that doesn’t seem to me to coincide with a God who’s full of mercy’. “
