Then I suggest you take a broader view of 'them'.
Generalizations are never a good thing. Yeshua is with them they can't be all bad.
Oh, but my view is quite broader than yours. My
space opera interpretation takes in to account things yours do not. Below you can find some examples:
1. Sacrifices (animal and human)- extremely common all around the world, especially at some cultures taken as to have been in contact with the alien false gods (ex: Mayas, Aztecs, Incas). What sort of benevolent sentient creature would be pleased with the suffering and death of other creatures? Why would they need these sacrifices?
2. Reports of modern abductions (and some ancient tales) indicate proceedures which are quite similar to the way we handle livestock (tags, invasive examinations, selective breeding) at conventional farms and also at game farms.
3. The constant analogies made by Semitic religions comparing people to sheep and the (false) gods to shepperds. We know the ultimate fate of lambs in the hands of shepperds, don't we?
4. The thin veneer masquereding the antropophagic nature of some Christian rites is easilly removed. Its all about blood and flesh... And they were built over the influence of your fellow Jesus/Yeshua, who by the way every now and then also used refferences to sacrificial lambs. So yes, Jesus/Yeshua was one of them and it can be all that bad.
I can go on. There's much more. Humans are livestock for the aliens; providing brute slave workforce and food. They come in every now and then, check their cattle, count their numbers, give them some food/vitamins/medicine (ex.: mana, angel hairs), pet some of them and grab some others for food (ever checked the number of missing people at police records?). When the time comes, they will, as stated in most religions, descend in large numbers from the heavens. Sheepish humans will wellcome them and flock to their ships to worship them, to bask in their lights, to beg for bits of wisdom and solutions to the world's problems. And they will be happy to serve their masters.
So, how would you like to be served when the alien sky demons land?
Now, can you show your interpretation is better than the above fantasy? Of course not. Can you imagine the reasons for your failure?
Crap, I should have been hired to write the backstory for the new V series. I bet I would do a better job than whoever came up with the material they presented. Rapture and feeding time.
