Could someone explain how a file can be modified before it is created? Thanks for your time.

The file modified and created dates are simply an additional text string included in the file.  Upon being created the file should have the created date set and when saved should have the modified date updated.  It is easy for a user to manipulate these values if they really wanted to.  Also, many programs may not include the functions to update this information.  If you are using something like Microsoft Word, it should for the most part keep track of a document, but if you open it with any other 3rd party software it could mess up those values.

I wouldn't worry about the dates too much anyway, as they are only somewhat reliable.

Example of a program that can manually change Created/Modified/Accessed dates: http://www.nirsoft.net/utils/filedatech.html

As explained here: http://www.techrepublic.com/article/build-your-skills-learn-to-manipulate-file-time-stamps-in-windows/

It is possible that the act of moving a file can cause creation dates after modification dates.
