Silly presumptive pontifications
merely serve to alert others to the paucity of the pontificator’s ever perusing of the plentiful data on the topic.
You bet.
In all of creation, the Lord did not make all the billions of galaxies with their attendant stars for the amusement of people on this rock.
However, I do think that it is just a little, no make that a lot, humerous, to envision an interstellar craft, no doubt of extraterrestial shape and abilities, to "disguise" itself by placing freakin running lights on the fenders so as to fool those who might catch a glimpse into thinking it is merely an airplane, just before they enter light speed and zoom out of view.
They could just as easily kill the lights, and go stealth, unless they wish to signal to other --->real aircraft<---so that they can be avoided?
Do you really believe that? If you do, then some of that paucity is between your ears.
