His argument was that because this civilization is supposedly from the Zeta Reticuli system, the naturally occurring materials there may give them an automatic leg up, mainly if 115 was a plentiful source there. He argued that not everyone will start with the steam engine and evolve from there, but that maybe these crafts could be their first experiments. How he explained them coming to our world and observing us, maybe impressed by the way we do things, was pretty funny.
I'm also intrigued by just how small these crafts supposedly are.
Ah ok . I have not listened/watched yet.
