let's think for a minute

For years now we see endless disucssion about ufo and government. Let's say, for sake of argument that there are alien spaceships from other planets or dimensions or whatever visiting Earth regulary. I honestly can't imagine why they would botter except if we were kind like a zoo but let's go on. So, the aliens are were.
Now let's all pause for a minute and think: Which is worst, that they are were and work with our governements for whatever reason? Or that they are were and our governments don't have a clue why? In fact that they can't do anything about it and the only reason the aliens haven't taken over the planet is that they simply don't give a dam about it or us?
