Some 5 billion years from now, the Sun will expand and become a red giant. And the Earth might be just in the way... If humans were still around then, would we leave the Earth? Or would we move it? What is the Sun's problem anyway?

Like any other star, it has an expiration date. The beginning of its end will feature our Sun swelling into a red giant, wiping out everything that happens to be orbiting it too closely. Like the Earth.
