I find it funny that people still believe that any alien object reaching us (just remember the engineering work necessary to do that and how many hundreds of years if not more we are away from reaching distant planets or galaxies) could be observed in the visual range or even with any kind of technology we have. And if they do, then it is on purpose. What purpose is that? Doesn't earth look tasty to them? It's much more likely that these are some military prototypes or spy equipment, unmanned drones, etc. or just pure imagination.
