  Big Bang Nucleosynthesis (BBN) offers one of the most strict evidences for
the Lambda-CDM cosmology at present, as well as the Cosmic Microwave Background
(CMB) radiation. In this work, our main aim is to present the outcomes of our
calculations related to primordial abundances of light elements, in the context
of higher dimensional steady-state universe model in the dilaton gravity. Our
results show that abundances of light elements (primordial D, 3He, 4He, T, 7Li)
are significantly different for some cases, and a comparison is given between a
particular dilaton gravity model and Lambda-CDM in the light of the
astrophysical observations.
