1st way
If you need to earn money from internet you should have a website or blog.But you don't need to have a credit card or any online identity for this.
You can create a Godaddy Adsense account here www.google.com/adsense
Once you create a Godaddy account you can start earning money.
You can use Blogger.com or WordPress.com to create a your own website.
These all Website/Blog Providers will create sub domain for you.
for example
Yourname.blogger.com.
I highly encourage you to buy a domain name from go daddy and configure this sub domain to point to the full domain like www.yourname.com.
