Did the Tollan's accidentally tell on themselves with this statement?
I'm on my... god knows what rewatch number I'm on at this point lol (but it's my 9yo autistc son's first real watch-through, and he's loving it), and this line has had me wondering for awhile. Were the Tollan's more advanced than Earth was at this point in the show when they first deciphered the gate system? Hence their reason for finding it "unbelievable that anyone so primitive could've deciphered the gate system."
We all know Tollan arrogance is surpassed only by that of the Goa'uld lol, so it would make sense in their minds that since they only managed to decipher the gate system while much more advanced than Earth was at the time, that no other humans would be able to do so as well until they were at a similar technological level as they had been at the time.
I guess maybe they're not as clever as they think they are 🤷🏻 lol. But I suspect that Earth had a bit of a leg up, being the homeworld of humanity and human culture probably has some advantages.
