Ancient supercontinents and Earth's first inhabitants, aliens, a lost planet and twenty vanished civilizations

What is inside the book?
Did you know that our planet Earth looked different than we see it now? Most of the globe was covered by water, and later relatively small pieces of land began to appear, which formed the first continents millions of years ago. At some point in the development of life on Earth, these continents were inhabited by the first humans who built civilizations. In the course of further development of the Earth, new continents appeared, and others disappeared under the water along with people and the civilization they built. This book tells how our planet was formed, what people and highly developed civilizations existed on it in ancient times. The book is well illustrated and can be recommended for reading by adults and children.
