Part of the function of WordPress will detect the page you create and assign from the Settings >> Reading options in WordPress. So if you are creating a static front page and a blog page, then set both of these from the Settings >> Reading options, WordPress will send all blog posts to that page you created and assigned. Then with your menu, make sure you have a custom menu created and then add the static front page you made, plus the other page to the menu. When I make those two pages, I will normally call the one I did for the blog as “Blog”. Also, note that when you create the page for the blog, you simply title the page “blog” and thats it, no content needed and no page template needed.
