We are their economy, and they don’t travel through space. They travel using their minds. Have you ever read “Dune” ? Human beings are farmed, because among other things, are thoughts create a kind of useable energy for them… just like the movie “The Matrix.” I know it’s hard to believe, but not all of our fiction is actually fiction. In fact, the truth is far stranger than what I have just written. Nice writing, by the way. Good job introducing a new perspective. Thanks.
