If humans were to die out could natural geologic processes completely erase all traces of our civilization or will there be something left behind that could last billions of years?

Plenty of things would last billions of years.

We have preserved bacteria mounds that are almost 4 billion years old. Tons of them.

We have preserved raindrops and dinosaur poop that are hundreds of millions of years old.

We have preserved leafs, footprints, insects, worm tunnels, jelleyfish, and so on.

Now look at what humans have done:

We have carved through mountains all over the globe to build roads and mines. We have strip mines which can actually decapitate entire mountains, or create gigantic pits in the ground. We have collected many common and rare minerals (and elements) into solid refined chunks unlike anything found naturally. We have spread our trash throughout the oceans and through much of planet's landmasses too. We have diverted rivers, built dams, spread radioactive isotopes around the soil layers of the planet - we create a new-endless stream of junk that we collect and bury into massive dumps which will leave unmistakable evidence behind.

Until the planet is obliterated, strong evidence humans were here will be present to anyone that looks hard.
