Reasons for belief

There is a survey here being run by Duncan Colvin as part of his postgraduate research at Goldsmiths under the supervision of Prof Chris French, on why people believe or disbelieve certain things.  I tried but gave up at the first slide.  I had to indicate whether I believed or disbelieved creationism, and my top 3 reasons for believing or disbelieving it.  I thought straight away of the reasons scholastics might give for believing in the eternity or finitude of the world, constructed as three arguments for, three against, a long discussion for or against, followed by 'replies to the main arguments', and then realised any reply I gave in the little boxes on the survey would be sadly inadequate against such a standard.
