Here is an example of a page. It is different from a blog post, in that it will stay in the same place, and will be displayed in the navigation menu of your site (depending on your theme). Most people start by writing an About page that introduces them to potential site visitors. You could write something like this:
Hello ! I'm a mechanic who aspires to be an actor, and this is my blog. I live in Bordeaux, have a great dog named Russell, and love vodka-pineapple (and watching the rain fall).
...or something like that:
123 Machin Truc was founded in 1971, and has been providing the public with quality contraption ever since. Located in Saint-Remy-en-Bouzemont-Saint-Genest-et-Isson, 123 Machin Truc employs 2,000 people, and manufactures all kinds of cool stuff for the Bouzemont community.
As you are a new WordPress user, you should go to your dashboard to delete the current page, and create new pages with your own content. Have fun!
