OK, let's stipulate for a moment that the thought that a rock created life is superficially absurd.
Equally absurd is inventing a belief system predicated on an unseen sky-daddy that created it (out of what and from where?), sans any evidence.
OK, so now I'm done stipulating anything except that the universe exists and lacking evidence to the contrary, we're going to have to figure it's origin out without skydaddy, who's a deadbeat of epic proportions.
A scientist doesn't get insulted by either of these prospects. We just go to work piecing together the cosmic data and trying to see what that data and our understanding of the rules can tell us.
The funny thing is, the earth is so freaking young compared to universal age, it's 3 generations plus some slack just counting stars like itself. Throw in hot/short-lived stars, and the estimates go up to double-digit estimates of the number of stellar generations possible in the 10+ billion years before Sol was ignited.
From these earlier generations, supernovae create rarer elements. Give them literally hundreds of millions of years to a billion years to spread around and recoalesce and form another star system.
In each new star system, collect that stuff into planets. If the planet has fluids, things'll mix nonstop. With very little time on a planet with fluid components, all sorts of compounds form. Oxides. Carbonates and Nitrates. Tons of other molecules. Small organics (hydrocarbons, mostly). Let them group up via natural sorting mechanisms (erosion, siltation, wind-wash, crystalization, freeze/thaw cycles). Bombard these with the occasional external burst of energy (fire, lightning, or that sort of decay of adjacent material).
There's an old saying: nature abhors a vacuum. In the case of thermodynamic economics (how much energy in, how much energy out), this is applicable because any time a reaction can either release a lot more energy or happen more efficiently than another and trigger at a lower potential energy, it will. Stuff that burns, will. Stuff that oxidizes, will. Etc. So, about the time that some complicated compounds form that don't have an easy release (don't burn, don't oxidize, don't dissolve), they'll accumulate. And when something comes along capable of exploiting that energy, it will.
More complex mechanisms? Same gradual increase in complexity. When an organic compound forms that rips apart secondary compounds for energy and similar organic compounds as residue/waste, the process becomes self-sustaining. Let it fizz and expand for even a few years and it'll spread until it consumes every such resource on the planet and then 'dies off' (no input, no output... but not technically dead since the limiting factor is a lack of inputs. Every time something generates a few more tasty molecules, they are short-lived, being ripped apart by our fizzy proto-life compound. When a few such fizzy protolifes exist and happen to overlap in a way that fizzy 1 eats 2, generates 3 which eats 4 and 2 and generates 1, you've now got mechanisms that cycle. Let them cycle for decades or generations. New cycles form. After a few thousand years (not much needed), there are literally hundreds of these cycles, and the number of complex compounds is growing.
The first 'life' would have been this sort of cycle, accomplishing little more than molecular dissolution of something. Something simpler than an enzyme acting on a bunch of hydrocarbons, maybe. I'm not a biologist: ask one what they'd consider the lowest example of life. ... get what I'm saying? It ain't a ROCK that creates life. It's statistical improbabilities that boggle your mind being bested by the sheer quantity of material and time: 10^50 atoms and time for them to undergo 10^20 reactions apiece (former # googled, latter one is an ass-pull: a possible reaction every few seconds).
Yeah, there's gaps in our model. Again, I'm not a biologist so I'm not sure where the gaps are. I've always been curious about them, but not enough to ask around. I see that DNA is inordinately more complicated than methane, for example.
But the gaps to our understanding are fewer than a decade ago, and far-far-far fewer than we were carrying around a century ago. And so far, the need for divine involvement ain't the theories making inroads. And while the universe has a 15 billion year head start, we've got more time ahead of us than we have in recorded history: we'll keep exploring and trying to understand, I hope.
T/L; DR: Go ahead and get pissed all you want; the 'insult' is undefeated. Sorry. And I don't need faith: I just look back at history and the remarkable successes of the scientific process. I **trust** it, because it doesn't say I have to believe 'a rock created life' or not. Scientific knowledge just says what is so.
