Posts as Blog Page

Hi,
I am building a website using the free version of the blackbird theme. I am unable to set my posts to show up as a blog page. I tried to change it in the Reading settings by selecting ‘a static page’ in the front page displays and setting the front page to be the home page and the posts page to be the blog however the ‘home’ page does not show up as a page in the pages section so I cannot do it this way. Can someone please help me resolve this issue? I would really appreciate the help. Thank You.
