The Writers' Circle

We are not sure exactly when they arrive, but we think it wasn't that long ago. We are still trying to study their technology but it is going to be hard to accomplish considering the situation. We have managed in the preceding months to download their records and translate them. That alone has been a monumental accomplishment involving tens of thousands of linguists from around the world. We used their last entries to find common experiences we could recognize by their pattern. It worked and we are now sure we know what happened to them just before and after they arrived. Further progress into the translation is required before we can figure out what happened before then.
     We do know that they arrived from a distant solar system using our space bound radio signals as a beacon to guide their way through the unimaginable vastness of space. It was such a long journey that hundreds of generations lived and died knowing only the confines of their spacecraft. This was a journey they were very determined to make, but, as of this time, we still don't know exactly why they did it. We have found over two thousand spacecraft so far and are trying to locate any more that we may have missed.
     When they arrived, they landed their craft on a lonely stretch of beach somewhere in the Caribbean.  No one noticed their arrival, hell we were lucky enough to discover them at all. They quickly unloaded their equipment and started to build a colony there. They were soon attacked by beasts several times bigger than themselves but had enough advanced technology to fight of the hostile creatures. 
     Eventually they had enough time to build several magnificent cities and just enough time for the last of the space faring generation to die off before disaster struck. It must have come as a complete shock to them when the sky came falling down upon their race. It killed every single one of them and destroyed all of their cities.
    And we would never have known they had been here at all if Safi Tyros hadn't died. They found a strange purplish fungus looking thing on the bottom of his left foot when the autopsy was being performed. It was then that we accidently made the discovery. 
     The fungus was their tiny version of bacteria and they were rapidly consuming Safi's body. Their bodily remains and the destroyed fragments of their cities were quickly discovered among this sea of fungus.
     The aliens were microscopic, only a third the size of an amoeba and their entire civilization could easily fit inside the eye of a needle. They were destroyed by Safi as he made his way down the beach. Their remains were lodged between his toes and he didn't even know they were there. 
     The tiny alien bacteria soon finished consuming the aliens and moved on to consuming Safi. As soon as they reached his bloodstream they quickly started consuming his heart. If this hadn't had occurred, as fast as it did, Safi might have washed them all down the drain.
     I can't help but wonder, if Safi hadn't walked exactly where he did, if we would have ever eventually crossed paths with these microscopic visitors. I can't help but wonder.
