Many things about the entire situation remain confusing, even to this day.
As an example, after the initial fallout following their arrival had subsided, where did the creatures go? Given only speculation remains as to their eventual fate, was the government involved, or had they simply vanished as mysteriously as they arrived?
Or are they living amongst us still, hidden from the prying eyes of the general populace by those sworn to protect them?
Perhaps we'll never know, just as it's as unlikely we'll ever be told the real truth as to their mysterious presence in our world. The government has covered it up, the people involved remain mute, and the creatures themselves; these pokemon; are the biggest enigma of the lot.
At least their presence here has answered one important question that's plagued humanity since the dawn of its creation.
We are not alone.
Perhaps we never had been.
