There's just a bit too much human self importance in that statement for a duck to be making Realistically We know there are planets that can support life out there. So in a Verse created with pseudo-science why wouldn't this be true?
Who says that there's only life on Earth? All we know is that you can't get further than there in the NN. Doesn't mean that that's all there is.
it's not and it's not. re read the woj again; the NN orbits worlds other than earth in other realities.
- for example, the canim, the marat, the people of the sun'..
And for all we know; there are other NN's.
and we know there is intelligent life from outside the NN, the vord came from there.
the problem, imo, is getting from one 'magical space' to another; without magic, you have to use tech.. like the vord did.
while FTL may exist in the Jim verse, there is no evidence yet that it does; even his most advanced species uses, by star trek standards, very primitive technology.
so to some up: our NN contains within it all the possible earths that might exist on the spectrum of free will, including ones in which human life never even evolved.
ga zillions and ga zillions and ga zillions of worlds
there are other alien worlds out there, that are not in our NN, as they are to far away.
(the vord homeworld)
and probably ga zi;llions and ga zillions more
while its possible those worlds may have ,magic and NNs of their own, Jim has not said so yet that I know of.
