The accepted source for those who have purportedly abducted humans is not other stars, but other dimensions.
This goes back to the point in time at which Allan Hynek stopped being a skeptic and became a believer.
Whether these aliens are real or not, they are commonly thought to be extradimensional (less than a millimeter away, not light-years).
In the Twilight Zone, Rod Sterling claimed that dogs had the capacity to sense those adjacent dimensions. Actually Sterling was wrong. Squid has the sensory capacity to sense and communicate with those adjacent dimensions. You are going to have to learn and speak the beautiful language of the squid. What nonsense! Believing in adjacent dimensions is just another way of exercising the mystical capacity of your brain.
