Observations from the James Webb Space Telescope (JWST) have unveiled several galaxies with stellar masses 
at redshifts 
. These remarkable findings indicate an unexpectedly high stellar mass density, which contradicts the prediction of the 
model. Our study utilizes the Chevallier–Polarski–Linder (CPL) parameterization, one of the dynamic dark energy models, to probe the role of dark energy on shaping galaxy formation. By considering varying star formation efficiencies within this framework, our analysis demonstrates that in a universe with a higher proportion of dark energy, more massive galaxies are formed at high redshifts, given a fixed perturbation amplitude observed today. These intriguing results highlight the promising prospect of revealing the nature of dark energy by analyzing the high-redshift massive galaxies.
