Sorry If these questions are stupid, I was just randomly thinking about how rna started.
In: 329
I thought nucleopeptides were created in the natural uranium reactors deep underground back when the earth was still hot and water was liquid in aquifers only. or am I thinking of something else

Well a few things.
1. When you have random RNA being generated, the chances of it forming a self replicating molecule are ridiculously small. When it happened on earth, it took potentially a billion years.
2. The conditions that existed on earth when life developed no longer exist. There are no longer blood-warm seas filled with tons of organic molecules. There may be some RNA being randomly made, but much less than during Earth’s early history.
3. Assuming a new form of life did spontaneously generate, it would have to compete with the existing forms of life. We know that when life first evolved, it wasn’t very efficient or “good” at living. It took a long time to evolve into the modern rugged, adaptable, and fast replicating forms it has today. A new form of life would probably get bullied out of existence by existing life forms.

Yeah, RNA can be created randomly in pockets, but since there’s already life on Earth, that life will quickly consume the RNA strands, not allowing them a chance to eventually turn into life. The early Earth had no such “predators” (as it were) so they were able to change over time into life.

RNA is easily created by random reactions. But it probably isn’t producing living things frequently. That process took a while on Earth, and we’ve never observed it to have happened anywhere else.
Even if it did, it would almost certainly be out-competed by existing life, which has had billions of years to evolve. We know this because all known life today appears to descend from a single common ancestor. That means no new life in the billions of years since that ancestor has managed to compete well enough to survive in a world of existing life.
