It is said there that the root of this big universal banyan tree is on the top; therefore history begins from the top. Yes. This planet comes later on. We can take the idea from the tree - the tree grows gradually, and the different fruits, branches, and twigs gradually appear. Therefore it is to be understood that this planet has grown later on. Besides this we understand that although the planet was later on grown up, it was covered with water - pralaya payodhi jale, merged into the water after devastation. Then gradually it emerges from water. That we can experience, that gradually land is coming out of the oceans. Because of its being merged into water, it is natural to conclude that the beginning of life was aquatic.
