Changes

: There are different kinds of '''evidence ''' but scientists don't trust all of them.: In science '''evidence ''' must be [[repeatable]]. If you make an observation or measurement once, you should be able to do it again and again and the result [[results]] shouldn't change.: In science '''evidence ''' must be [[reproducible]]. So if one person makes an [[Observe|observation ]] or [[Measure|measurement]], every other scientist in the world should be able to make the same [[Observe|observation]]. If they cannot ; then scientists don't accept it as good evidence.
