Hi,
BuddyPress depends on WordPress. Have you installed WordPress on your hosting account?
If not, I would kindly say this is a WordPress issue. Try reading this article to install WordPress:
https://codex.wordpress.org/Installing_WordPress
If that article is greek to you, Hostgator should have some form of customer support; it should be quite easy for them to setup WordPress for you.
If you need additional help, please head over to the WordPress support forum:
https://wordpress.org/support
Once you have WordPress setup, all you need to do is to login to your WordPress admin dashboard and navigate to “Plugins > Add New”. Then, search for “buddypress” and install.
^ *As all listed on the codex page. 
Not really! Codex page doesn’t say install WordPress 
Well I was assuming he was meaning buddypress because it was posted on the buddypress forums….
But because he was talking about *host* he could of been talking about wordpress- it was unclear.
Thank you for the help, I think I figured it out.
