It's hard to say for certain that there has never before been an intelligent species. Over hundreds of millions of years even evidence of cities (even assuming that all intelligent species would even make cities) could be entirely wiped away.

Shout out to the Silurian hypothesis. It’s been linked here many times, so I won’t link to it again.

especially true if you consider that if there were hundreds of civilisations scattered across the Universe, the average distances across space and time would still be hundreds of times larger than we could deal with right now, or perhaps ever

for a civilisation with advanced rocketry and telescopes similar to what we have right now, it would still be very unlikely to observe us - firstly because we've only been around at all of a tiny fraction of the time the planet exists, and secondly because despite of all the ruckus we are currently causing in the planet, we'd still be very hard to observe from sufficiently far away

I have all sorts of deluded fantasies regarding U-235 found in gabon.
