Viracocha above the Portal of the Sun
So was Viracocha from another world? It would seem so by this account as none of the native people had fair skin or red beards and wore white clothing.
Viracocha Stella monolith
The Inca believed that their creator deity rather than a civilized society much older than their own made monoliths such as these in the Semi-Subterranean Temple.

Viracocha seems to be a celestial teacher of an extraordinary sort and his so-called offspring may be the officers who served under him. No written language of Tiwanaku survives. Did they have a written language that we have not discovered? We know the people of Tiwanaku used the khipu.
What we have that might be the written language of Tiwanaku is in the symbols that they left behind.
Tiwanaku monolith statue
As you should notice, this monolith has symbols carved into the skirt. These marks could indicate the figure’s importance; they could be astronomical or astrological symbols, all of which could be notations and hence writing.

The people of Tiwanaku left these symbols on their monoliths and this may have been their written language whose translatability is now lost. I strongly suspect that is what has happened. Since we barely understand how to translate the Quipus (or Talking Knots), it would only make sense that the language of the Tiwanaku would be hard to decipher or translate too. Because these symbols definitely have a meaning.
Side view of monolith statue
You will note from this view you can see symbols on the monoliths belt, on the arm a tattoo and an armband, and the hat on the head seems to have some symbols carved into it too. Could the belt be a power belt of some sort? As you can see condor symbols and there may be symbols of Viracocha on it as well.
Relief on the top of the Portal to the Sun
On the Portal to the sun, Viracocha in the center signifies the spring and autumn equinox (the longest days in the year). There are forty-five birds on this relief most probably condors. At the bottom, there are small carvings of Viracocha at each full moon. At each end on the bottom is a representation of the solstices. Their year began with the first full moon and ended with the last full moon. Therefore, this part of the Portal of the Sun gives us Tiwanaku’s year. The New Year for the Tiwanaku is June 21st. The Aymara have preserved this tradition.

Therefore, from this evidence we can infer that the Tiwanaku did have some form of simple written language carved in stone. However, we need to find more evidence if we expect to decipher these symbols.
