...Explain the "only getting life from life" thing again. At one time there was no life on Earth. Do we agree?
At one time there was
no Earth.
So, yeah. I'm sceptical about atheistic concepts of life from non-life.
I can only say that your only hope of getting past that unreasonable skepticism is to take a course in molecular biology and evolutionary mechanics.
The issue is that you have this idea in your head, "life". It doesn't really mean anything, it's just an expedient with a fuzzy edge. It's an imaginary line, a piece of categorical trivia that we all put too much stock in and need to step back from.
It's all still "just" chemistry.
It just happens that when someone thinks something is "dead" generally the chemistry is less interesting.
Are viruses alive? I guess they are, if you say they are... Are prions alive?
The fact is, all it is is fueled cyclic reaction.
Now, there's a caveat to the next thing I'm going to ask: accept that you are wrong. Not necessarily accept that I am right but first that you are wrong. I will do the same.
What part of the chemistry do you not understand? Do you not clearly, really, understand what the early earth could have been like?
Think of all bthe wierd stuff that you see. Most of it is made from hydrogen, oxygen, carbon, nitrogen, sulphur, phosphorus, sodium, chlorine... Pretty much "every chemical that spews out of a volcanic vent that isn't silicon or metal. But some do that too.
The earth spews everything we are made of. And everything the plants are made of. And when the earth was young-ish, it had already spewed quite a lot of what you see. But it wasn't shaped like it is now, today. It couldn't be. It was like that water of your book, formless and void, full of energy with nowhere for the energy to go.
That energy manifests physically, via volatile chemistry and motion, and most of the oxygen was bound to carbon. Eventually cyclic chemistries are bound to arise in that where various reagents start to get consumed. When that process burns out, eventually a new equilibrium is reached in the chaos and a new chemistry starts until that burns out, and so on. This is a demand of entropy! Eventually, one of those explosions of organic process, not necessarily something you would call life, is going to create a byproduct that interacts with other littered byproducts of various chemical eddies in a way that you WOULD call it life.
