The Outliner shows a list of all the objects in a scene, it's not set to show every little thing by default but that shouldn't be the issue here. Are any of the objects you created grayed or dimmed in there (in the way that the default cameras persp, front, side etc are)? If so, then the object is hidden, select it/them and hit shift+h (show selection) and see if that works. Also, there is a "Show" menu among your panel menus (right above your 3D viewport), click it and make sure that particular type of object is checked on, in this case, I'm guessing "Polygons".

If not then upload the file to a hosting site (google drive or whatever) if possible and link it here or in a pm.
