One more post for the day...sorry.

32. Based on

what I know about the universe currently (which is of course a layman's level), I do not think these objects that have been witnessed over time have traveled here from other places through space. I say this simply because of the distances involved, and the currently understood limits in the physical realm. The size and distances involved simply cannot be be understood by scale in the human mind, even as much as we think we have a grasp on it, it's still bigger. We can compare to known examples, but that still doesn't put it into true perspective.
IF these objects are not human invention (general reference, not about the drone thing), I believe the only possibility is something else that we currently consider sci-fi, which is dimensional travel, objects from other planes that we are not even aware of. There is a lot of fringe theory about it, but still just wild speculation. I just can't see how travel through space from another galaxy, or even the other side of our own, is physically possible. So I am left with theory.
The easiest and most probably answer is that these are human created vehicles, and that is what I believe is going on with the drone thing right now. Most photos show nothing more than distant lights, and the ones that are close-up and blurry show standard navigation lights in required configurations. I personally believe this is our own authorities searching for something, a something they are unwilling to share with us at the moment for whatever reasons.
