The latest research shows life may be 3.8, or even 4.1 billion years old, not 3.5 as shown in the Circle of Life. See here: https://en.wikipedia.org/wiki/Evolutionary_history_of_life
This matters greatly since the earlier life began on Earth, the easier it presumably is to establish. This has profound effects on our expectations for life on other worlds too, as we ramp up our collection of Earth-like planets in the galaxy and beyond.
Please consider updating the origin of life date in your model.
