Nah. Humans aren’t remotely that powerful. We could detonate every nuke on the planet tomorrow and make human life impossible, but in 1000 years the conditions for life would be fine, just the large animals would be extinct. In 1 million years you wouldn’t even know it had happened u less you dug I to the geological record. And 1 million years is like the blink of an eye on the timescale of a planet.
