think it is referred to as a sticky if you want the home page static

The first page will end, but your website is going to be an ever-evolving and changing thing

Some good answers below

Your blog roll will likely have about 5-10 posts in it. You can change this in Settings > Reading "Blog pages show at most", and you can also change from full text to a summary if you want (I prefer summary)

I'm thinking your theme doesn't have a blogroll and it shows the whole page of each post. If that is something you don't like, you may want to consider changing your theme to one that has a snippet of each blog. You can also what Katie said and do a static page.

as the first page is a rolling blog it is not set out like a word document when you do a page it goes to the next, you can make the page static if that is what you want

Your website is never done you will be adding post after post creating awesome content on each and everyone of them.

Do you mean that if you continue to write will you eventually reach the end of the page?

Umm... what do you mean by this? :)
