Where did you get 10 billion years of random chemistry?

The articles I read assert that life began just 500 million to 1 billion years after formation of earth. 3.5-4.1 billion years ago with an earth age of 4.5 billion.

The universe is about 15 billion years old, and chemistry didn't start with the formation of Earth.
Chemistry in earth certainly started with the formation of earth.

Are you suggesting that abiogenesis didn’t start on earth, but self-replicating molecules started evolving in earths protoplanetary disc?

Serious question, haven’t encountered that theory before. It’s kinda panspermia-lite.

Kurzgesagt did a video on this recently https://m.youtube.com/watch?v=JOiGEI9pQBs
I believe you may discussing at cross-purposes.

Presumably like your parent, I believed this was a discussion about the probability that life has originated elsewhere in the galaxy / universe, independently of life on Earth.
