what if they do not even have to travel from another galaxy to us. what if they are extra dimensional, and live in the same location as us, just in another dimension / universe, just shifting over to our plane , without having to travel a gajillion lightyears even at light speed which would already take infinite energy to achieve. wouldnt it be easier for them to use said infinite energy to break the boundary into our spacetime? extra-dimensional aliens are more feasible than faster than light travel. even if they got it, it would take generations to reach us.
