Hans-Joachim Zillmer like Immanuel Velikovsky is an advocate of Catastrophism, however, in connection with a special Young-Earth-Theory, the Young-Earth-Catastrophe-Theory suggesting that the Earth as a planet is old indeed, but was struck by a global catastrophe (deluge) about 5000 to 6000 years ago. Whereby the catastrophe incidents including reactions setting in and successive catastrophes happened over a longer period of time, in which the effects were regionally chiseled variably forceful. Thus, the utmost North of Europe and North America escaped the very worst devastation. By this catastrophe horizon our earth’s crust was significantly remodeled and rebuilt. The geologic core thesis of it is, that there have been several super floods pouring out on the continents: the North America’s South-, and Northwest, across Australia, or from the Altai mountains across Siberia all the way into the Caspian Sea, the Baltic Sea and into the Arctic Sea. With that, a shifting of the axis of the earth occurred and only at this point in time the by him so-called Snow Time the icing of Arctic and Antarctic areas as fast motion like, shortened Great Ice Age (Pleistocene). During this time according to Zillmer the earth’s gravity increased also, and animals existing in a „mega format“ so far, like the elephant size giant sloth in America, the giant stag or the mammoth in Eurasia, died out. Thus, a new world with smaller animals emerged, different atmospheric conditions e.g. decrease of air pressure („Darwin’s Mistake“, 1998, P. 149) and an elevated gravitation
