I went to a biology/astronomy talk where there was a researcher working on the sequence of chemical changes on the early earth without much water or atmosphere would need to create dna base pairs. It was stunning because they basically had a sequence of things and geological discoveries point toward the precursor chemicals being available. It's not that dna was just there. This is not "life arising spontaneously". Th…
The “eventually build dna base pairs” (that continue self replicating) is the uncertain and possibly ludicrously improbable step. See for instance https://www.nature.com/articles/s41598-020-58060-0 which argues for a probability per exoplanet small enough that it hasn’t happened a second time in the observable universe. On the other hand, one of the self-organizing proposals cited elsewhere in this thread may turn ou…
I'm a software engineer so I don't readily admit I don't know what I'm talking about. Are you in the field and can maybe elaborate on your skepticism? This fellow was pretty certain they've worked out several likely possible paths. This was last year.
