A practitioner asks: “Why did Creator make viruses? By what mechanism did they serve humans before they were manipulated by the interlopers?” What can Creator tell us?

Viruses were created for all sorts of reasons and there are many known facts about viruses available in your science which you can Google to learn examples. They were not created specifically for humans directly but as an aspect of consciousness in having a wide array of life forms. There are many useful viruses in nature as well as strategies for an interplay that helps in having an overall balance of life within Gaia. For example, there are viruses that can inhibit bacteria, and this is a part of the ongoing balance in ecosystems. The fact that viruses can be manipulated by sentient beings, like the extraterrestrials in your midst, to cause disease in human beings and other creatures is a perversion no different than turning canines into attack dogs that might be quite dangerous when on the loose.
