I thought that with your vast scientific experience, you would be able to fill in the implied hypotheses without needing them spelled out.
One example of a hypothesis implied by A, B, and C would be: “Ores on Mars can be turned into almost 100% pure metals by the normal workings of natural laws and/or chance incidents such as asteroid strikes or earthquakes.”
It should be possible for an experimentalist in geology, materials science, chemistry, etc. to test that hypothesis by subjecting ores to various simulations of events that take place on Mars. (artificially generated impacts with the force of asteroid strikes, radiation bombardments, etc.), and recording whether such events generate enough free metals (iron, aluminum, copper, etc.) in one location to provide the casing for a machine such as the one described. Or even just by leaving ores lying around, as they do on Mars, and seeing if any “natural law” regularly or even occasionally causes e.g., iron oxide (fairly common on Mars, I believe) to separate into pure iron and pure oxygen.
And if the earth environment isn’t suitable, soon we will have robots good enough to run the tests on Mars. For example, the robots might find that there was a huge rise in free iron (or some other metal) in the vicinity of asteroid impact craters, as opposed to spots far from asteroid impacts. So the machine might have somehow come into existence by using the free iron (or other metal) near impact craters. On the other hand, If they found no appreciable amount of free metal on Mars anywhere, then the hypothesis that enough free metal to make a metal casing for a machine could be generated by asteroid impacts would be disconfirmed.
Another example of a hypothesis to test: “Electronic circuitry and working lights, radar dishes, etc. can be produced without any design, if you let an iron oxide desert be bombarded with ultraviolet rays long enough.” That’s in principal testable. If we find partially assembled machines all over the surface of Mars, in various stages of completion due to being started at various points over the past few billion years, that would tend to confirm the hypothesis. On the other hand, if we find nothing but rocks and dust all over the whole surface of the planet, and nary a machinelike part in sight, that would tend to disconfirm it.
I’m sure you are quite capable of generating more hypotheses of this nature, to test A, B, and C. And I’m quite sure that you privately believe that such testing, if carried out, would rule out those three hypotheses, leaving only the design hypothesis as a credible explanation of the mechanical gadget. Not that I expect you will ever admit to that private conclusion here.
