This prediction has happened. In 2015 we originally predicted that water would be found on Mars. Then in 2017 history was made. Last April Spirit claimed a large body would be found and now that has arrived too! Spirit has also predicted that life exsist in our own back yard in the form of bugs and sea creatures, where the rocks float. That could be seen as Saturn or the Asteroid belt.
This prediction could be our rock message: Prediction: Mueller Findings Spirit showed the words NOW on a large rock.
Notes on 3-10-15 Mars “History in the making.. water!” Spirit’s Voice
