Astronomers believe in the existence of Dark Matter in galaxies (GDM), a hypothetical form of gravitating substance devoid of atomic and nuclear structure. The problem is complicated by the appearance of Dark Matter entities in the Lambda-CDM Big Bang Cosmology. We conducted a critical analysis of current phenomenological GDM models in comparison with Newton’s physics. Attention was focused on a controversial criterion of the possible existence of GDM in “Keplerian” vs “non-Keplerian” galaxies. As a result, we suggest an Alternative in the Newtonian Gravitation framework. It ensures a GDM-free treatment of galactic observations, provided the interaction of Core and disc appropriately accounted and some concepts of Galactic Dynamics reviewed. We also studied the interfacing of GDM with “Dark entities” (Cold Dark Matter and Dark Energy) in the Lambda-CDM Cosmology and concluded that they were introduced for different reasons and our criticism of GDM conception does not essentially affect the Lambda- CDM status. A success of the Newtonian Galactic Dynamics is illustrated in examples of the Milky Way and other galaxies. We state that the work contains novelties of fundamental importance, among them is the main one: the proof of GDM being fictitious.
