In about a billion years, our local star will get enough brighter to cause the oceans of our little planet to boil away, so we really don't need to wait until the sun runs out of hydrogen and starts to expand radically (out to or just past the orbit of Earth) to find the neighborhood no longer what it used to be.
Besides, even if we could come up with the technology to live further out in the solar system or even to send humanity to the starts, it's not that likely that we'd live that far into the future anyway. Humans haven't been around for all that long compared to some dinosaur species, but even they didn't last a billion years. If we last another hundred thousand years or so, we will have had quite a nice run of it. Given how we have been as stewards to the planet, we probably won't last
nearly that long.
