  If you want a root user by default use another OS than Ubuntu that uses the root model. CentOS, SUSE.

In Ubuntu by default, you cannot log in as root. You log in as a user and providing you are in the sudoers group, which will be the case for the user you create during a new installation, you can run a command as root using the sudo command before the program or action you want to perform. For instance.

sudo apt-get update

There is also the option of typing sudo -i in a terminal and after entering your password you can start a root shell. But you should only do this if you absolutely need a root shell for some reason.

The user root already exists by default when a Linux system is created, or at least, a user must exist with UID 0 who has all permissions and owns most of the system files. Traditionally this user is called root. You do not need to create that user.

When you install Ubuntu, you are prompted to create a user for yourself. This is because it is inadvisable to run the system as root, because root always has all permissions and programs run as root may do whatever they want, which is a security risk. Running commands and other programs as an unprivileged user wherever possible is safer. But, the user you create at installation is not limited in their rights. That user is automatically made a member of the group sudo and is allowed to run any command as root by using the sudo program. This means you can make use of sudo to do anything you want on the system, even to run whole shells and other programs as root, as SteveInBavaria pointed out.

Ubuntu is slightly different from many other Linux distros in its approach, because it disables logging in as root by not setting a password for root. On many Linux systems, when you want to elevate privileges, you become the root user by typing su - or just su in a terminal. The su (switch user) command allows you to log in as another user in a shell. You must enter the password of the user you want to log in as, not your own password. On Ubuntu su fails because root has no password. You can "fix" this by setting a password for root, but this is discouraged and not necessary since sudo provides all privileges. You can even run the su command as root by typing sudo su. Then you type your own password and become root. However, since sudo provides a way to open a root shell there is no need to run the su program with it for this purpose. You can simply use sudo -i.
