Page order on WP Admin [edit-pages.php]

Newbie question.

My apologies if this has already been covered. I could not find it.

How can I set the order in which the Pages are listed in the edit-pages.php? When I go into the Admin section/Manage Pages all of the Pages I created seem to be listed in a random order. I have tried eliminating all plug-ins.

What is this listing based on by default and can it be modified. I thank you in advance.
