They’re here and our navy pilots have been seeing them for years. I do however believe they haven’t made contact. Why should they — just look at our world and our species. We have yet to evolve to what I would call a civilized member of a functional interplanetary group . Ergo the Supreme Court decision to prohibit refugees from coming here, not hosting the victims of Hurrican Dorian, (which we in the US probably caused with our greedy use of coal, oil and gas), refusing to enact gun laws while our children die, denying people health care because they don’t have enough money to pay for it -but here I’m getting boring, and the list of human barbarities to the members of our own kind would take up pages and pages of print.
My next two books, currently in production, in my climate/science fiction series (theburningyears.squarespace.com), allow me to imagine who and what they are, and the energy they are using to reach us from this dimension or from parallel universes (think Tesla).
It also allows me to imagine how we might evolve with a little help-re zero point (economics) not culture or politics (colonialism)- from our visitors. My theory is we’re in quarantine until we either destroy our earth or figure out a way to save and get along with her.
Oh and there are probably universes and time dimensions out there where they might be coming from that we haven’t figured out yet. Stay tuned!
