That's a stretch...cows know of humans, they know specific humans, they fear the slaughterhouse in many cases. They may not understand their ultimate destiny, but it seems a vast stretch to imply our buried-in-the-ground corpses are being eaten by ultra intelligent aliens.

That is exactly what I mean. We, the not ultra intelligent specie might not have even a clue about how they could benefit from raising and harvesting us :)
Maybe that is what some people call faith/religion. Some believe it, some disregard it as low level primitive behavior.
