Suppose we go to Mars and come across what appears to be a highly advanced technological device of extraterrestrial origin. Let's call this object X. Would the claim "X was designed" be falsifiable? That is, if we assume that the hypothesis "X was designed" is true, are there any testable predictionstestable predictions that could be made such that if those predictions are shown to be false, the starting hypothesis that "X was designed" would be shown to be false?
I'm proposing this thought experiment in the context of recent discussions about the scientific status of Intelligent Design, whose primary focus is the apparent design observed in biology. Likewise, if we observe apparent design in an object found in extraterrestrial conditions, would it be possible to establish scientifically that such an object came about by design and not by natural processes?
Clarifying what I mean by testable prediction
By testable prediction I mean inferences of the form: If X is true, then Y should be expected to happen or have happened, such that we can arrange some sort of experiment to verify whether Y actually happens (or has happened).
In this particular example, testable predictions would be of the form: if this extraterrestrial object was designed, [fill in the blank] should be expected to happen (or have happened), which naturally raises the question: what would we expect to happen or have happened if an object was indeed designed as opposed to having come about by natural processes?
