i cant find "add page" in create content

Hello everyone ,

i am absolutly new to drupal (using drupal 7.12 on a localhost) and content managment systems in generall. I´d like to try around and learn , but for me half the content options seam to be missing , for examle there is no "add page " in my create content menu.

I ´ve been searching tutorials and forums since hours , but all i find is " to create a new page , go to "create content/add page" ...well , there is not " add page " for me :(

i have all available modules enabled

this is what i see :
Navigation:
add content:
-Blog entry
-Book page
-Forum topic
-Poll
Forums
Recent content
Feed aggregator

Administration

the same under administration/sturcture/content types , only blook blook forum and poll

i´ll be greatfull for any help
