N2 - Astronomical observations strongly incompatible with the canonical cosmological model are reviewed. In particular too early formation of galaxies, as discovered by HST and JWST, is discussed in detail. Other data revealing highly dense population of the very young universe with plethora of other different types of objects are presented. It is demonstrated that similar or maybe even more pronounced problems can be seen also in the present day universe. It is argued that all of the above mentioned problems can be nicely fixed by assumption that the universe is filled with primordial black holes in wide mass interval from a fraction of the solar mass up to supermassive BH. The mechanism of PBH formation presented in 1993 is described. The predicted by this mechanism log-normal mass spectrum of such PBH is shown to agree very well with the data. Finally possible rich population of our Galaxy by antimatter is discussed and new ways of its identification are presented.
