Absolutely. Because of very plausible possibilities like that is why I hold off on appealing for the existence of a super- or para-natural layer of reality, I think the natural layer is incredible enough.
A thought I had re our back and forth about viri and wildflowers was the concept of
grey goo: "
Gray goo (also spelled
grey goo) is a hypothetical
end-of-the-world scenario involving
molecular nanotechnology in which out-of-control
self-replicating robots consume all matter on
Earth while building more of themselves,
[1][2] a scenario that has been called
ecophagy ("eating the environment").
[3] The original idea assumed machines were designed to have this capability, while popularizations have assumed that machines might somehow gain this capability by accident."
In some respects Life on earth is a green goo; self-replicating the shit out of itself everywhere. Some models even have the little green replicators surviving the impact that created the moon.
Maybe the ETs are monitoring the Earth to make sure we (the green goo) don't manage to make it off and contaminate the rest of the cosmos. Ever wonder why we haven't been back to the moon? Perhaps the PTB got a stern warning to stay in our yard...
I remember Drexler's book -
The Engines of Creation . . . makes me wonder if there is a poetry department specifically for popular science books to supply the titles or whether they use something like this Popular Science random cover generator:
Science Magazine Cover Generator :: The Slightly Disgruntled Scientist
hours of fun . . . one cover generated had a headline of "hot, naked nanostructures on display!"
Just a few from a top 100 listing of popular science titles:
Lonely Hearts of the Cosmos
A Brief History of Time
Pale Blue Dot
The Alchemy of the Heavens
Brother Astronomer
They used the grey goo concept in the remake of
The Day The Earth Stood Still - an entirely bad sequel that is yet not an entirely bad movie on its own . . .

Not too long ago, Richard Dawkins became excited (agitated?) over some compelling telepathy experiments - then he realized that if a natural explanation for telepathy were found, then telepathy wouldn't be a supernatural phenomenon! Immediately after this, he reportedly went to his underground lab to look at hot, naked nanostructures.
If there is a supernatural layer of reality, then by definition we can't get at it by empirical methods . . . maybe we can point to it in the way we think of a singularity, an event horizon, but we would never be sure
empirically that something lay beyond, because of the possibility of a new approach. So what we would have are logical arguments but mainly persistent intuitions.
And either there is an error in thinking that you can conceive of something outside the natural . . . you can certainly make that statement - but what pictures and conceptions come up when you hear the phrase "the supernatural" - seem to vary greatly from person to person, so perhaps the mystic is only someone with a peculiar kind of imagination?
On the other hand, these persistent intuitions have always come paired with persistent intuitions to the contrary - in other words, materialism has always had its mystics.
I think it's not an entirely good idea to discard intuitions of something else -and here I mean the sort of thing that seems to bring many people to this forum . . . if you use the evolutionary argument that such intuitions can be adaptive without conforming to "reality" then you have to consider applying that same argument to materialistic intuitions - one of Plantinga's arguments but also for the wisdom of "dancing with them what brung you".
The trap comes in when you come back to say yes, but we have empirical evidence to support materialistic intuitions - true, but only to support some of them - empirical evidence isn't complete and it very possibly cannot be complete (otherwise you vote for a type of omniscience) and two, you've got the circular argument that only materialistic intuitions
could be supported by evidence . . . (evidence/absence redux) and three, you have to account for the evolution of a brain that both detects reality and makes gross errors in judgement - when Ockham might suggest the more parsimonious answer that it actually does neither.
