i know how to make new blocks, but i want to put new blocks on like different pages...like a blank module page that i can add blocks onto

Hi, im new to the content managment world. I want to learn how to make my own pages/modules. I just want like a blank page, like the home page, where i can add blocks and such, but i dont know how to make it. Help would be greatly appreciated thanks.

Also, an unregistered user to my site or an unlogged in user cant see any of my pages or the content on my front page, if i could get some help with this it would be greatly appreciated. Thanks in advance.
