Compatible Os

When people trying to teach how to use UNIX OS, they always use UNIX compatible OS such as Solaris OS or Linux?

What is the original / real UNIX system. Where can I find a step-by-step tutorial and the original unix download links. I am not referring to compatible UNIX OS. I really mean UNIX as in UNIX or is there no such a thing to begin with?
