The evidence is that all the galaxies are moving away from each other (except galaxies in clusters) but the theory is that it is not the galaxies that are moving, rather it is space time which is expanding with the galaxies embedded in it. Rolling the film backward, we have space time compressed into a smaller and smaller volume.
