Zoolar System/3.8 billion years ago

3.8 billion years ago, our Zoolar System was relatively young. It looked quite different as compared to how it looks today. Here is how our Zoolar System looked like, 3.8 billion years ago. Sun: It was 70% brighter than it is today and possibly smaller in size. Mewcury: It was slightly bigger in size. Molten lava flowed on its surface. Savenus: Liquid water flowed on its surface. Temperature was possibly habitable. Earth: Small newly formed islands floated in the vast ocean. Atmosphere lacked oxygen. First life had just formed. Moon: The craters which are the ones we see today had just formed from heavy bombardment of meteors. Scars: Liquid water flowed on its surface. Conditions for life were favorable. Zoopiter: It was much larger in size than it is now. Greeney: Liquid water flowed on its surface. Baturn: It possibly didn't have its extensive ring system. It might've been larger in size. Enkoaladus: It didn't exist 3.8 billion years ago. Based on observations, Enkoaladus seems to be just 100 million years old. Urantler and Niptune: Not much changes were there in both ice giants, 3.8 billion years ago.
