Abstract
A review of observational data from the Hubble and James Webb space telescopes, and ALMA array is presented. It is argued that the discovered contradiction between the observational data and standard ΛCDM cosmology is resolved if the Universe structure formation is seeded by primordial black holes. The proposed scenario is supported by the agreement with observations of the predicted log-normal mass spectrum of primordial black holes and the discovery of a significant amount of antimatter in the Galaxy.
