Science can be subdivided into two categories, ''operational science'' and ''origins science''.<ref>Sarfati, Jonathan, and Matthews, Michael, ''Refuting Evolution 2'', [http://www.creationontheweb.com/content/view/3256 Chapter 1]</ref>
'''Operational science''' deals mostly with things in the present, which scientists are able to observe, measure, and test. If, for example, someone claims that water boils at 110 degrees Celsius at sea level, you can test for yourself to see if that is really true (and discover that it's not).

In some cases, such as astronomy, the distinction between the two becomes somewhat muddled; strictly speaking, current observations of most astronomical phenomena are dealing with the far-distant past, but experiments and observations are easily performed - it is common for a theoretical prediction to be compared with observed data.
