As to why they would come? Who knows? Maybe they find it interesting to watch a civilization develop. Especially one on the verge of space travel.
Maybe a trip to earth for them was like a trip down to Australia for Darwin.

Even if the distance aspect was somehow figured out (which I would think would be almost impossible), you would also have to hope that those species and civilizations exist at the same moment in time as we do... and by moment, I mean on a cosmic scale. At least on this planet, species only last a for fleeting moment (and it's possible and even likely the same thing applies on other planets).
You would have to hope that not only another planet in our galactic neighbourhood developed life, but also that they learned to manipulate the laws of physics, but that they also did it at the same fleeting moment that human civilization exists.
