Airbender extinction makes no sense

Of all the benders to have been completely wiped out, wiping out airbenders is just not logistically sound.

Yes, Sozin’s comet is extremely powerful. But also, they’re airbenders, and of all groups they would have the mobility to be able to escape. The idea that not even some escaped just doesn’t make sense.

I love the show and it’s not that serious to me, but I did wanna say something lol
