mikasaga on "use the Pages as parent files?"

Hi!
i'm tryin to learn how to use the wordpress blogs by creating my own and i'm facing a problem : i would like to write all my articles inside the pages (at the beginning, the only one is the "About me" page that i deleted, and created other pages instead).
However, it seems we can write articles only on the main page of the blog... do you know if it's possible to use the pages as parent files, by the way i could write articles inside these pages.
Thank you for helping!!!!
