The latest geological conception of the genesis of karst terrains, published in respected Springer's journal Carbonates and Evaporites, suggests that the entire Earth's surface was covered with water about 5,000 years ago. The conclusion is derived based on the the analysis of depth of micro karst landforms (karren), which are by this concept, the only karst features formed under atmospheric conditions, i.e. by diluent effect of rain waters. The results represent a serious attack on scientific theory of evolution, which certainly could not happen within 5,000 years.
