If there were alien spacecraft cruising the either, at super high velocities, wouldn’t we (possibly) be able to see (detect) the high energy “contrails” from the vessel.
Where are all the linear “streaks” of particles; where are the “bow waves” made by the ships interaction with the fabric of space ?

This is actually one of my favorite arguments to toss at UFO/abductee woowoos:

You need to expend a hideous amount of energy to accelerate to anything NEAR lightspeed; you'd need to expend the same amount of energy to DEcelerate from those velocities. Where then are all the brilliant IR signatures created by all the (alleged) alien spacecrafts' engines? I'm pretty sure we'd eventually notice any matter/antimatter reactions going off in the neighborhood.

Suitably subtle use of tractor and pressor rays can muffle sonic booms and the like. Let's see. The aliens have tractors, pressors, radar nullifying (or amplifying--it's not completely consistent) shields, hypno beams, and some sort of magnetic drive. Sometimes these drives are completely silent, sometimes they make a wierd noise. Sometimes they have flashy lights. These things are a bit unclear.

What is clear is that they have serious anal and bovine fetishes.

Which should make them quite popular within certain subcultures...:D

Given the high crash / explosion rate of UFOs, I think its high time we instituted an Earth No-Fly Zone. It's only a matter of time before one of these jerks hits us at .9C Just try claiming on your insurance for that.

I wonder when will the first absent-minded alien forget that it is crop circles and cattle mutilation, not the other way round.

Are you kidding?

They'll just claim that the saucers "use the vacuum energy all around us" and that by "shielding gravity" and such that there's really NO extra energy required, at all.

Logic will not work when confronting woo-woos.

As many others have said here already, if you can postulate that aliens are making their way here from parts unknown, then you can overcome absolutely any technical objection. If you're going to invoke magic, let it be deep magic.

Which is why P&T's Shock-value skepticism is a very, very good thing.

Obviously the aliens see in gravitons, which allows them to make their voyages almost entirely on gravity assists.

And they're patient. Very patient.

If you were to have a ship say, about the mass of an essex class aircraft carrier, and accelerate it to .9c, then you'd be looking at plenty of energy on deceleration.
