After reading the synopsis it seems Battlestar Galactica used the plot instead, sorta.
chances are BSG creators got the copy of the pitch at some point
Well, it certainly fits in with the whole ancient astronaut origins of the original BSG.
They all copy each other, Stargate copies Star Trek, Star Trek copies Stargate, Star Trek copies a different Star Trek show, etc
I don’t mind. I love it all.
and then there’s For All Mankind
What about it? I didn’t really see it as sci-fi. It was more just speculative what-if fiction, as nothing really went beyond our own technology more than an accelerated decade. I liked it. It got a little McCarthyist towards the end. That’s why I don’t even bother with Star City.
it’s an acute reminder that RDM had a point while Star Trek ended up with the muppets.
