There are a few reasons why you might not be able to see your selection in Illustrator. One reason is that Illustrator is a vector graphic editor, which means that it can only handle images that are in the form of lines and rectangles. If you have an image that is in the form of text, then it will need to be converted into a vector format before it can be used in Illustrator. Another reason why your selection might not be visible is because it may have been hidden behind other layers or objects in your document. If you want to see your selection, you will need to select it and then click on the Show Selection button at the bottom of the window.
