I know virtually nothing about CS, which may be an advantage in seeing the sense in your thinking in abstract. If we assume that humans are conscious & material, without bothering to define either, we at least know it is possible to have consciousness embodied in something material. At least in theory we could figure out how human consciousness works and replicate it. There may be easier ways, but this is at least one theoretical possibility. You could in the same way have inferred that humans could figure out a way of creating flight from the fact that it exists in nature.
