The Earth is estimated to be around 4.54 billion years old. 700 billion years ago, our solar system and the Earth itself did not exist.

Here's a timeline to help you understand:

* 700 billion years ago: The universe is very young, and the conditions that would eventually lead to the formation of our solar system hadn't yet emerged.

* 4.54 billion years ago: The Earth is formed from a swirling disk of gas and dust.

It's important to remember that our understanding of the early universe is based on scientific theories and observations. We're constantly learning more about the history of our universe, and these timelines are subject to change.
