  In astro-ph/0601489, within the framework of the Einsteinian general
relativity, we made the observation that if the universe is described by a
spatially flat Friedmann-Robertson-Walker (FRW) cosmology with Einsteinian
cosmological constant then the resulting cosmology predicts a significant dark
matter component in the universe. Furthermore, the phenomenologically motivated
existence proof refrained from invoking the data on galactic rotational curves
and gravitational lensing, but used as input the age of the universe as
deciphered from the studies on globular clusters. This claim has been
challenged in astro-ph/0603213. Here we show that the raised objection is
invalid. It, at best, constitutes a trivial consistency check. As such, we
stand by our analysis, and by our conclusions, without reservations.
