They won't care. 10 million years after we wipe ourselves (and unpleasantly many of them) out, it will be hard to tell we ever existed, aside from the dip in fossil diversity right after. The raccoons might take up the yoke of sentience.
I chuckle thinking about future sapient trash-pandas discovering human landfills and worshipping the Ancient Ones who very clearly created this bounty for them. "They were so prosperous they put boxes of food on every street corner for our early ancestors."
