I understand what you mean, but having debated with Christians and observed how they try to twist words, I no longer use the word 'believe', instead I use 'accept'. I accept a scientific consensus on a subject because other scientists have also performed the repeatable experiments and obtained the same results. And as mentioned, if one really didn't accept, or 'believe', a scientist, one could perform the same experiment. Now I know the average person doesn't have a particle accelerator, but if one wanted to, one could study, become a physicist and actually get a job at CERN and use a particle accelerator or become an astronomer and use radio telescopes.
The trouble is, every single creationist I've debated with doesn't want to do this. Maybe because science is difficult. Even just to refute their ideas I have had to learn a huge amount of biology, astronomy, physics, etc, which I must say has been absolutely wonderful. My knowledge of the natural world has increased massively over the past few years because of creationists and for that I thank them.
As a starter, try to get hold of the US series 'Cosmos' with Neil deGrasse Tyson and also another US 3 part series called 'Your Inner Fish', all absolutely fantastic. My eldest daughters 10 and 11 love it. That's their ages by the way, not their names.
