Off sorry for being late, but if you're on mobile, just look up the article you want to make, and if the name of the page isn't taken there should be a sentence at the top of your screen saying, "the page called "example name" doesn't exist yet, something something you can make it." or something like that. If it is taken, you'll have to use a different name, or you could just do "example name (venusian)", in order to differentiate your page
