Creation Story of the universe can be described as a Big Loop which include many nested loop systems. Will start with a loop that actually describes how Earth and Creatures created.
Brahma as all know is Shrushtikarta, means he have the ultimate power to creation. The time of Brahma will start after a Brahma Kalpa. Brahma Kalpa is like replacement of Brahma. When new person take charge as Bramha he will pray Lord Vishnu to give powers to make creations. Lord Vishnu will give powers to Brahma to create universe.
Initial stage of the universe will be in the shape of Golden Egg this Egg is created by Bramha, so Bramha is also called as Hiranyagarbha. This Egg will split into two parts, top half will become 7 Oordhvalokas and below part becomes 7 Adharalokas. This completes first stage of Srushti.
Then comes other creations. Since Brahma can't handle everything, he will create few assistants. First Bramha creates 4 sons Sanaka, Sanatana, Sanandana and Sanatkumara. But they refused to assist him in his creation process and proceed to be in Bramhacharya forever. Then Bramha creates 9 sons together they called NavaBramha and they are, Marichi, Atri, Angirasa, Pulastya, Pulaha, Pratu, Bhrugu, Vasista and Daksha. Narada is considered as Bramha Manasa Putra but will not take part in Srushti. Then these 9 sons of Brahma carried Srushti.
Pratu one among nine sons of Brahma had assigned with the task to find a suitable place for Srushti. He searched all locations to find a suitable planet. Then he choose planet Earth to continue Srushti. Because Pratu found this planet, so this planet is named accordingly Pruthvi.
This process will be continued only when Brahma will change. Between this change there will be again small Srushti. There is also a case where Srushti will happen only on earth. This will be at the end of all Yugas. There are different ways of ending to all creatures on this earth. This depends on how many times all 4 Yugas repeated. This small ending is called as Pralaya. In a normal case, Jala Pralaya will happen. In case of Jala Pralaya, Markandeya Mahamuni will prepare a big Boat, big enough to fit all life samples in it. Then he will collect all life samples in it and tie that boat to Mainaka Parvata. After the end of Jala Pralaya, he will start the Srushti again.
There is more to explain but less time. I have just mentioned basics of Srushti. You can find different explanation in different scripts. What I have given is from Bhagavatam. Still there is lot to explain, but I too have less info with me.
