Within a few dozen million years UV radiation levels will be too high for us to survive on the surface with exposure to sunlight in our current form (at least without suits).
Within 600 million years the earth will be too hot to sustain life at all.
Within 5 billion years the earth will be consumed by the expanding sun (which will have become a red giant by then).
About 2 billion years after that the sun will go supernova, destroying most of the solar system and becoming a white dwarf.
With global warming most of the earth could become uninhabitable for human life in as little as 300 years. And there are likely natural and cosmic disasters in the future that our species will face that we don't know about yet. I'm confident we'll be long gone by then.
So yeah that's basically our cosmic timeline as far as the earth is concerned.
