A blog can have both "pages" and "posts" -- or just "post" with no "pages".
The following image shows the "edit pages" menu.
The "pages" are normally linked across the top, using the "pages gadget" which automatically handles the linking for you.
The following image shows the "edit posts" menu. Important: The top post (most recent) is the "home page" for the blog. The other pages need to be linked in the right sidebar, using the "links gadget". You build the links yourself.
