I don't know. Maybe we will be the seed of a galactic civilization some thousands of years down the road? If we get our priorities right and don't kill ourselves first.
Sure, but they won't be human, and speciesists care too much about that.
Then again, it's possible that someone saves human DNA and decides to bring us back from extinction one day. I'm betting on someone doing that with the Neanderthals in a several decades. So why not homo sapiens sapiens too?
