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.
- seszett 3y agoThe universe is about 15 billion years old, and chemistry didn't start with the formation of Earth.
- wingspar 3y agoChemistry 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.
- lovemenot 3y agoI 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.
