Visitors Welcome!

I've been watching NASA (UFO) footage most of the morning, and I've come to
three conclusions...

1) There are various different kinds of craft and they all seem to be 'aware' of each other.
This, in my opinion, means that every other (possible) species in the universe knows of each
others existence. We are the only ones in the dark.

2) These are, for the most part, some very large craft. Very large as in, travelling longer distances
with more people on board. Which leads me to conclusion number 3...

3) They appear to hover near Earth and the moon. They seem entirely interested in our planet and
our species. Why are they there, and what do they want? Considering the size of their crafts, I'd
say they have NO home to go to, and that perhaps there aren't any more planets as habitable and
life sustaining as earth.

It's very possible that something happened that destroyed more than a few homeworlds, but somehow
earth was spared. Maybe these beings stick around for the water and the fresh air. They leave
their crafts occasionally, but in the end, they are refugees/moochers and they are following some
code that prevents them from just coming down and taking over.

Maybe whoever owns this planet is still around and carries a big stick.

...curiouser and curiouser....
