Redirecting posts in WordPress to a specific page

Hi,
I created a page so that it would appear in my navigation menu. This page would however be my posts page (i.e. all posts would go here) and would also be my front page.

I am unable to find anything other than editing the ‘Home’ in the theme file (none of the themes I tried had the ‘Home’ editable). I’m looking for something that would redirect all of my posts as a stream into my homepage that also has a link in the navigation menu.

I tried looking at a lot of places for help in this, however I couldn’t find anything useful.

Thanks!
