"The day our sun becomes a red giant and swallows the Earth will be close to the time the stars will have receded leaving an all dark starless sky, and then it will be too late to be creative."
Not true for two reasons:
1) The main sequence lifetime of the Sun is roughly twice its current age so the universe will have expanded by a about factor two.
2) Although the galaxies are moving away from each other (some caveats, locally the Andromeda galaxy is approaching because of the gravitational attraction between the two), stars in our galaxy are not. They are evolving, but not receeding.
