Compelling is in the eye of the beholder.

Assume a scenario where an alien race of an extreme intelligence level above ours that we share this universe with comes to our humble planet. They too are omnivores and have found us to be a tasty food item.

This is where I start to have suspension of disbelief problems with the scenario. Even if some quality of the universe causes all life forms to use chemically similar forms of DNA, ISTM that the odds are that separate paths of molecular evolution would leave each race full of biochemicals that the other(s) find unpalatable if not toxic. At best, I'd expect us to make potentially useful sources of exotic organic chemicals.

One of my favorite bits of the background color in Sid Meier's Alpha Centauri is the incompatible biochemistry between Terran animals and Planet's lifeforms.

If we became aware that these aliens were eating us our number one desire would be that they stop eating us. We also might want them to go away and stop the food processes and infrusructure that they built up around us. We would not care so much how quick and painless the death process was when compared to the process as a whole. Most of the aliens might not even care if they could even be aware of our complaints.

Our number one desire would be to convince others that it's really happening.
