That is proof of nothing. Even if you took all the satelites on earth and the ones we have in space we STILL are only able to watch a fraction of whats going on in space around us. How many times have you heard all of a sudden they just found an asteriod hurtling towards us and it wasn't seen till it was almost on top of us and then it passes. Fast, just like that.
