Hello,ecuagranel!
In order to have a separate page for your Blog posts,
first, since you already have a static Frontpage,
1. You need to create a New page for your Blog (Dashboard->Pages->Add new),
title it as you want,(e.g “Blog”) don’t insert any content to it !, and publish it.

2. After you created and published your new “Blog” page, go to
Dashboard -> Appearance -> Customize->General->Static Front Page tab menu
and open it.
3. From the “Post Page ” drop-down list select your newly created “Blog” page to display as your post page.

4. Go to the Customizing->Menus->Your top menu, and add the “Blog” page to your top-menu.
