From what? And how?From various sources. They have been shown to form naturally.
I'm not sure what you're trying to say?
Are you suggesting that a series of chemical reactions took place; and that those compounds lasted for millions of years until one day they all came together?
If that were the case then why wouldn't these compounds be all over the place, especially considering all of the bio-matter that has piled up all of the planet from terminated plant and animal lives?
From the molecules present on Earth after it had formed from the stellar material left when the sun formed within a stellar nursery.Out of what? Where do the acids come from?
It's gotten much less shaky in the last forty years and still remains the only reasonable possibility.
I believe the idea (anyone can correct me if I'm wrong) is that for a period of millions of years, you have pretty much the entire earth's surface where different chemical reactions can take place. And the vast majority of those reactions won't create life, but all it takes is for it to happen once, at one place, at one time, before it starts reproducing and eventually spreads across the planet.
At least that is what I have heard.

Well, something happened, because there is life on the planet now, and it hasn't always been here.I just don't believe it. I'll wait until it can be proven. I don't like to jump to conclusions.
Seriously? You do not know of the Miller-Urey experiment or that amino acids have been found in meteorites?From what? And how?
There is no inherent chemical tendency for a series of bases (three at a time) to line up a series of R-groups in the orderly way required for life. The base/R-group relationship has to be imposed on matter; it has no basis within matter.
If it could happen once by happenstance; why not again in a ideal lab environment?
Why do you call that "happenstance?" An orderly biochemical process is hardly "happenstance."If it could happen once by happenstance; why not again in a ideal lab environment?
I suppose it could, but I think the point is that it would be very improbable unless you had a lab the size of the entire earth running experiments for millions of years on end.

Not so. Take a look at the following to see how peptides and amino acids can self assembleFrom what? And how?

So in other words happenstance in a lab? That doesn't sound like science.
The interaction atoms according to known laws just like any other chemical reaction.
Well if scientists don't know precisely how life first started (and they don't), they can't exactly reproduce it except by trying a bunch of different things and hoping one of them works. But they admit that's an extreme long shot.
Yes. We seem to be going in circles on this subject. We have a hypothesis that scientists have been working on for over 70 years with no creation. Let alone being able to reproduce the results. It reminds me of when the alchemists were trying to create gold. I can appreciate their tenacity.
