I think the main indicator of intelligent civilization would be burial sites and memorial monuments. While 10s of millions of years of geological change would certainly make these hard to determine, an advanced civilization is likely to produce millions of these. Surely we would have come across some by now.

That was actually put to the test, by really thinking hard about it, around 2018, or so. By serious scientists, not van Däniken types, or similar. The conclusion was that we couldn't tell, between slowly milled between mile-high ice-shields and fluctuations of seawater-level alone. Maybe, just maybe there would be the chance of some monument surviving buried in the center of a 'kraton', but why? Do we build monuments there, now?
