Making posts appear on "Blog" page

I don’t know why I am having such a hard time figuring this out so hopefully someone can walk me through how to do it.

The theme I use is Alexandria, so my home page is set as the default layout for that theme. I have another page, my “Blog” page, where I would like all of my posts to show up on. However, I cannot figure out how to get the posts to show up on the Blog page.

If someone could please explain the easiest way to do this or link me to somewhere that does I would really appreciate it!

Here is a link to my site so you can see what I am talking about:
