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 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](https://philosophy.stackexchange.com/q/99684/66156) 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?
