You can still find dinosaur footprints if you look hard enough. They've stuck around, in old riverbeds and slabs of sandstone. They're a good thing to go hunting for when you've got a spare afternoon. And they're a useful reminder that nothing lasts forever.
So I wonder who's going to be finding our footprints in 100 million years time?
Hopefully some really smart humans. Or something that evolved from humans. People of some description.
Of course, the saddest thing would be if they couldn't find our footprints.
Because the planet has become a strange flooded world, where fish are the boss.
Or because Earth is now a too hot hellhole, noxious and gassy.
Or because they can't find the riverbeds. They're buried too deep underneath the shopping trolleys and bargain buckets.
Or because there are no people left to do the finding.
Now that would be a shame.
