I once had a vet, desex a dog on the kitchen table, we ourselves have different standards where lessor life forms are concerned.
And if they are post biological as has been suggested before, that also would explain the lack of regard for our primative bioforms.
Trying to rationalise "alien" motives from a human perspective is imo unlikely to yeild useful conclusions
My dog gets abducted, taken on board a strange craft and delivered to a bright lit strange smelling room when the first thing that happens is an anal probe......(to take his temperature)
Youd think a species that can put a man on the moon could find a better way to take his temperature than to shove a glass tube filled with mercury up his bum...............
Its all relative

Not just the earth, but also the solar system itself as it spins around the galatic core,and the galactic drift as it moves out from the 0:0:0 co-ordinate of the big bang.
But imo calculating these factors isnt too hard a thing to do.
You would need a TARDIS (time and relative dimensions in space) to do the job properly.
It would be easier to target your destination based on the systems star, and then home in from there.
Calculating where a star will be in a 100 years, or 100 years ago is not hard.
I personally dont think time travel is impossible.
the speed of time for example is variable not fixed, it can be dialed up or down
Good doco here
