THE MERCURY INCIDENT

First of all it was an accidental uncloaking. The reason was a sudden flur of Sun. The solar photon storm unveiled an ALLIEN SPACECRAFT. Anyway their cloaking technology explains why no telescope has ever captured a single image of that advanced machines.
Now, what are they doing there? They try to protect life across universe. For some decades they watch Sun. The anomalous recent activity of our star, explains their concern. They are here for a long time. There are many dangers in space, especially in our solar system, but the seed of life must live.
Well, illusions? Hm. No! There is a coverage. The reason is: PANIC. The humans do not tolerate even another human with a different skin color, how could they digest the existence of an allien race? Panic causes chaos. Imagine a planet exploded!
Of course there are more, may be stronger reasons, for that secrecy: NEW UNIMAGINED TECHNOLOGY. I mean MILITARY ADVANCED TECHNOLOGY! The facts nowadays shout. Are we going to close our ears?
