Almost all galaxies over the whole range of Hubble types are seen to host very massive objects at their centers, either massive and supermassive black holes (SMBHs) or very dense star clusters, called Nuclear Star Clusters (NSCs). In this talk I will present and discuss the two available theories ("in situ" or "migratory" model) apt to explain the existence of such compact objects in the inner part of a galaxy, focusing the attention on the difference between the two types of objects (SMBHs and NSCs) and on the possible observational counterpart is support of one or the other interpretation.
