I have picked it up from a variety of resources. One is the Origins of Life course on Complexity Explorer: https://www.complexityexplorer.org/courses/155-origins-of-li...

Basically, as my understanding goes, life is effectively as old as the Earth is. As soon as it cooled down after forming and had liquid oceans, life started, which happened just a few hundred million years after Earth formed.

There is the book Every Life is on Fire as well, describing how life began to dissipate heat in the environment of molecules in water being heated. That seems to imply life will quickly start in such conditions. (Note: I don't strongly recommend the book, as it has a lot of religious stuff in it and honestly isn't that well written, and I have mainly learned about the author's theory elsewhere.)
