We propose a simple cosmological scenario which explains why our Universe appears spatially flat, homogeneous and isotropic. We use the Einstein-Cartan-Sciama-Kibble (ECSK) theory of gravity that naturally extends general relativity to include the intrinsic spin of fermionic matter. The torsion of spacetime generates gravitational repulsion in the early Universe filled with quarks and leptons, preventing a cosmological singularity: the Universe expands from a state of minimum but finite radius. We show that the dynamics of the closed Universe immediately after this state solves the flatness and horizon problems in cosmology because of a negative and extremely small in magnitude torsion density parameter, Ω_S=-10^{-69}. The ECSK gravity, which does not introduce additional matter fields, therefore provides a plausible alternative to cosmic inflation. The observed spectrum of cosmological perturbations suggests that the contraction of our Universe preceding the bounce at the minimum radius may correspond to the dynamics of matter inside a collapsing black hole existing in another universe.
