Also why use biological drones for a long journey instead of mechanical ones that are well suited to long hibernations and high radios environments?
That assumes that the biological drones are created before the travel begins. It also assumes that such biological drones are not suitable for long hibernations, while on Earth such species do exist. It also assumes that they only make biological drones or mechanical ones, but not both.
We don’t know what we don’t know, or how far technology can go, so it doesn’t make sense to say “aliens can’t do this because we can’t” or “because we find it implausible”.
It’s just more likely for them to follow the rules of the world as we know them as it is the most parsimonious explanation. In science you have to be parsimonious.
I get where you are coming from, and I certainly agree that it would take a great deal of evidence for any of these more complex explanations to take hold broadly. Concrete quantifiable evidence has been very lacking so far.
