Sure, I suppose one can say that, considering we don't currently have working implementations; but as I stated previously, "Defining the capabilities of an advanced civilization utilizing our current understanding of the universe and relatively modest level of technological development as a benchmark is an interesting, but flawed methodology."
The list of current technologies that were once in the realm of science fiction is too extensive to present here, but it's ignorant to assert that something that's impossible today won't be possible tomorrow. Your cellphone says hello, and you better tell the US Navy that they're foolish for patenting anti-gravity warp drive technology:
Craft using an inertial mass reduction device.
From the patent: "It is possible to reduce the inertial mass and hence the gravitational mass, of a system/object in motion, by an abrupt perturbation of the non-linear background of local spacetime (the local vacuum energy state), equivalent to an accelerated excursion far from thermodynamic equilibrium (analogous with symmetry-breaking induced by abrupt changes of state/phase transitions). The physical mechanism which drives this diminution in inertial mass is based on the negative pressure (hence repulsive gravity) exhibited by the polarized local vacuum energy state (local vacuum polarization being achieved by a coupling of accelerated high frequency vibration with accelerated high frequency axial rotation of an electrically charged system/object) in the close proximity of the system/object in question. In other words, inertial mass reduction can be achieved via manipulation of quantum field fluctuations in the local vacuum energy state, in the immediate proximity of the object/system. Therefore it is possible to reduce a craft's inertia, that is, its resistance to motion/acceleration by polarizing the vacuum in the close proximity of the moving craft."

First, the crashed alien spacecraft wouldn't have failed during interstellar travel if the bodies and materials are recovered on Earth, but I digress. At one time it was science fiction to be able to travel into space, let alone re-enter the atmosphere. How is it, that with our rudimentary technology, humans can survive the fireball that engulfs their spacecraft on their return to Earth? Could there have been advances in engineering and material science that afforded us this capability?
Regarding the hazards of space travel, how do you know an alien civilization would even be susceptible to the same factors in space as humans? Again, extremophiles, as a very real "world" example of organisms that can survive, even thrive, in conditions that would kill most things. Have you considered that an alien race might not even be carbon-based?
As far as crashes go, how do you know any purported crashes were the result of space travel (and the hazards therein) in the first place? Failures happen. Nothing is perfect. It's not only possible, but highly likely that a systems failure (for any reason) could occur and in the context of a vehicle, might very well result in a crash.

The observable universe is quite large. Detecting omnidirectional radio signals would be contingent upon the broadcast power being great enough for the signal to even reach us. If you don't believe this, why do people suffer from weak wi-fi even within their own homes, for example? Beyond that, how do you know the signals are omnidirectional in the first place? Lasers by definition are highly directional and there's a lot of space out there. Unless we have direct line of sight to the origin of transmission and it's pointed directly at us, we won't be detecting much (including point-to-point radio transmissions.) Perhaps you fail to comprehend how sparsely the universe would be populated even with many multiples of 300,000,000 habitable planets? How do you know there are no other means of communication beyond what we currently understand? Lasers and radio broadcasts were once within the realm of fantasy too.

Also, why would aliens wish to visit Earth - a tiny grain on a nearly infinite beach? It seems pretentious and egotistical to think we humans are worthy of such attention.
Why is stealth necessary? During the Congressional hearings, the aviators were quite clear in stating that the technology they observed was far beyond our capabilities, in fact alarmingly so. If they're not worried we could harm them and they don't care if they're detected, what does stealth have to do with it? Are you saying that because they choose not to conceal themselves it's proof they have no abilities to do so?
Pretentious and egotistical to think we're worthy of such attention? Hilarious. Better tell that to the etymologists studying ants. Perhaps it's pretentious and egotistical to view everything through a rigid anthropocentric filter, decrying anything we can't currently achieve as impossible.
