As you say, it's time lapsed. That speeds things up; the sheep are faster than normal, the stars rotate in the sky faster than normal, any aircraft or vehicle would appear to travel faster than normal. If something flew overhead with a flashing strobe light, you'd expect to see a series of dots in a time lapse.
Maybe. Maybe not. When viewed from this end of the big picture we think we are the shiznitz and any other life forms that may be out there SHOULD be interested in us. When viewed from the other side of the known Universe we are invisible. Even from outside of our own Galaxy we would be invisible to anyone else. If such beings exist there is no credible reason they would be aware of us. We have not even reached out beyond our own solar system in any meaningful way. Our solar system is but one tiny one amid uncounted others just within this single galaxy, of which there are untold numbers of them of all sorts across the expanse. The number of worlds that exist is staggering and unknowable. We are not special. On the other hand, IF there are life forms within this galaxy, as in nearby on this same "arm" we inhabit then yes, I can see where we might garner their attention, if even by accident. There's no reason to assume that such beings would be benign, or aggressive. We simply cannot know what might motivate such beings.
