  We show that the observational universe may emerge classically from a de
Sitter background with low energy scale. We find, after calculating the
curvature perturbation, that the resulting scenario is actually a style of the
eternal inflation scenario, in which some regions will go through the slowly
expanding Galilean genesis phase with the rapidly increasing energy density and
become island universes, while other regions are still eternally inflating,
which will make the room for more island universes to emerge.
