Yeah I never liked the panspermia as a solution to how life started so quickly on Earth because it just kicks the can down the road. But hey it has been speculated that DNA may be almost 10 billion years old https://phys.org/news/2013-04-law-life-began-earth.html https://phys.org/news/2013-04-law-life-began-earth.html. But this is just a thought experiment, I am unsure if we know how long it takes for DNA to double, nor do we know if the rate would be constant over time. For example if proof reading mechanisms evolved later thus slowing down the rate of change. But it's fun to think about. Too bad Google search is so useless I used to be able to go down these Rabbit holes finding all sorts of information but now it's almost impossible, Google just gives superficial AI answers these days
