You can add your site to Google here:
However, note that Google and other search engines work by estimating how popular your website is, according to how many other websites contain links to it. If they find links to your site in other places, they will automatically add your site. If your site is not linked from anywhere, it will not appear highly in Google’s rankings. So, what you should do is find friendly website and blog owners and ask them to place a link to your website on theirs.
