hmmmmmmmm

That's an interesting question. I say yes, since Twilight Sparkle knows everything about everything. :P
And in previous generations, there were people in the show. But I guess that's hardly related...

Hmmm..... maybe, but I wouldn't want humans to get involved, because it would kinda ruin the show :(

Maybe who knows that's the fun

Only Lyra knows best about us people. She especially wanted hands.

They don't know much about dragons, who actually LIVE on their planet. How would they know about HUMANS?

I don't think so. But now they do.

There must be books or something on the subject in Twilight's library, right? Besides, what about Lyra?

you didint wach equistria girls??!

Twilight and Spike would know because they been to the human world in both Equestria Girls movies and she might have told the other main 6 about it when she got back. Plus in fiction where Lyra is obsessed with humans.

no with the exception of the mane 6 the 3 princesses lyra and i will take a guess that discord knows to

Hmm I think yes :3
