But it looks like there is a more mundane explanation.
Most people don't look up at the sky all that often. When they do, often times they see planes, birds or stars. Most of the time they don't think a second time about it and go on with their lives. But when they look up expecting to see something all of a sudden whatever they are seeing becomes significant, interesting and possibly alien.
As interesting as first contact with alien life would be, I'm afraid that this is not it either. If it is, then those aliens are a bunch of jerks buzzing our cities and mocking us.
