Sadly this really isn't the case, and there are a lot of things we can do that will permanently fuck the planet. It can't be certain that we will kill ourselves off before we cross some tipping point that will eventually turn the Earth into just another lifeless rock in our solar system.

That seems pretty arrogant that a hundred million years or more won’t restart life back on Earth. But I also might just be ignorant. What could we do to end all life on earth and prevent future life from forming?

Well, "permanently fuck the planet" can be a matter of perspective. The great oxidation event "fucked up" the planet for anaerobic life, but we would not exist without it, so it was a huge blessing for us. Even human CO2 emissions could be viewed as a huge blessing for biosphere in the far future since it releases captured carbon ("the currency of life") thus significantly delaying the timeline of atmospheric CO2 depletion to levels at which photosynthesis becomes impossible.
