Volcanoes are rather terrifyingly cool. The entire surface of a planet can wipe away all evidence of any life through volcanism alone. Magma outflows bury everything in its path and as the tectonic plates move about over time, all the buried rubble gets buried even deeper for any remnants that might remain.All evidence of our existence would be wiped clean off the surface in cosmically quick time, solar storms would destroy orbiting appliances which would succumb to orbital decay and burn up in the atmosphere as gravity pulls them back to Earth.
Quite remarkable how fragile life actually is and all it takes to wipe any sign of its existence is natural geology whether kick started via magma pressure buildup, plate movements or an asteroid impact event doesn't really matter. All have happened more than once on Earth and will happen again in the future.
Neat!
