The History of our planet

Our planet appeared already many millions years ago. Since the most ancient times to ours there was a set of theories how life on Earth arose as organisms developed and from them new appeared. However there are also other theories bound to emergence of the biosphere. For example I learned recently that there is a theory which says that water on our planet appeared not from the ice crystals brought on our planet and from the underground ocean which is at a huge depth in the planet. And before refuting any theory it is necessary to prove impossibility of its existence at first. Personally for me this theory has the right for existence. Also you should not forget about fauna on our planet, once long ago it was not similar at all to what we call fauna now. Instead of such creations as cats and dogs existed dinosaurs earlier, and sea open spaces were plowed not by sea horses and tarpona and huge megalodona. To the word of people mastered the nature still very poorly and explored only 5% of all ocean. How much we did not experience yet and did not see? It is possible that some types of ancient water inhabitants including megalodona could endure Ice Age having taken cover deeply. I consider that it is one of the most urgent problems today. The mankind has to know everything about the nature and on which about the planet it lives. But today technologies do not allow to explore many places on our planet yet. On the other hand you should not forget about what is out of our planet. There is the infinite number of others space objects and one of the close to us is the planet Mars. In 2030 the expedition is already planned for this planet for the purpose of its further colonization and development. If it occurs then people will be able to explore the planets following Mars after a while. Thus we see that the mankind achieved huge successes in all spheres already today. However all this huge contribution to development of humanity which collected during millions of years only the beginning something larger and more significant.
