We do not yet know all the laws of physics, time and space.
We get better at it, but have yet to crack many mysteries.
Perhaps we will one day. Those stars are out there for a reason.
Well, now that damn near everyone has a video camer how come we never see footage of a aliens or their aircraft? I mean, a big meteor will fly over and 2 or 3 people will get video of it. How come we never get film of flying saucers? Just curious.
