Aliens traveling in a spaceship at 99.99% the speed of light* could theoretically allow them to traverse hundreds of light years in a month. But because of 'time dilation', a month on that spaceship would be equivalent to thousands of years on a stationary planet. That's because traveling at that speed slows time down dramatically, but only from the point of view of the passengers aboard the ship. From the point of view of the aliens they left behind on their planet, thousands of years will have passed (in earth years).
So, here's my theory:
- Aliens either did not want to make the interstellar journey towards us because everyone they leave behind on their planet would be long dead by the time they return (because of time dilation)
OR
- Aliens DID make the journey towards us. The trip will take them just a couple of months, but those 2 months to the passengers on that ship is equivalent to thousands of years to us (again, because of time dilation). Therefore, from our point of view, they'll finally arrive in a few thousand years. From their point of view, it's just 2 months.
*Traveling at the speed of light is impossible
