theist is greek for something along the lines of 'believes in god' and atheist is the anti- of that (i think) but i used atheists as in the people who believe most of what scientists say...

take this example... ages ago when HG Wells' war of the worlds became a radio production many people believed it to be real because they tuned in late but in a way is that a belief? because they had to rely upon the radio to inform them of what 'was' happening they didn't know if it was for real and yet they trusted in it much like we trust in what scientists say about how the universe is made up or how christians believe the stories of the bible and muslims the koran
