It sounds too circular though. "It is, because it is." Justifying the existence of something, because it exists? Any meaning it has wouldn't hold. If you translate it that way, "It is what it is", that carries a different meaning. No longer you are asserting the existence of something, but accepting that something "is".
To say it in Spanish, you say "es lo que es". :P

Therefore, therefore therefore? Based on 'I think, therefore I think' and 'I am, thefore I am' would it not be safe to say 'I think, therefore I am'?

I'm very tempted to say one could use "ergo, ergo ergo" with legitimate meaning. It can be looked at as "it is, therefore, it is", or more familiarly, "it is what it is".
Sum cogito, ergo sum cogito. This language is easy peasy.
