Interesting. This basically goes to the idea of abiogenesis. Space like environment?
Hmm, some of the other amino acids and basic building blocks for RNA and DNA need an oxygen rich environment to form. Some others need a hydrogen rich
environment. Others have been found to form in conditions like that of a volcano. Other basic building blocks have been found to form naturally at the
bottom of the sea near thermal vents. Some need electrical sparks such as lighting to form which you don't have in space. So far, self replicating
RNA with the ability to mutate has only been shown to be formed in a lab in unnatural environments unlike this experiment and others that try to
simulate a more natural environment such as space with this one.
Unfortunately you can't have life without all the basic building blocks of life present or they wouldn't be basic building blocks. Then again I
wonder how many basic building blocks one really needs?
So far, all they've found is that they can all be formed in different types of environments. That won't work for the abiogenesis theory cause by the
time that RNA reached a non-space environment to combine with other basic building blocks that have to form in a non-space environment it would have
been destroyed. Even if it managed to crash land on an oxygen rich environment the basic building blocks that only form outside o an oxygen rich
environment would already been long gone by that point.
For abiogensis to be true all the basic building blocks to produce the first life form would have to exist at the same place at the same time. You
can't have some of them forming in a volcano, others forming in space, others forming at the bottom of the ocean, and others forming millions of
years apart from each other in an oxygen and non-oxygen rich environment and some forming where lighting exists and some forming where lighting can't
exist and expect they all just got put together in one big soup by chance.
It would be like making an omelet without the chef. You need someone to get the ingredients from where they are formed like a chicken farm and the
beef farm and the garden and the store and the bakery and put the ingredients together at just the right time and in the right place before they
expire and go bad.
If there's no chef then how did all the ingredients that formed at different places millions of years apart get put together to form the first life
before the ingredients went bad? It's impossible.
So the only way the primordial soup can be true is if scientists find an environment where all the ingredients can be formed at the same time under
the same conditions. You can't keep changing the environment artificially in a lab for each basic building block to make your experiment work because
in the real wold, environments sometimes don't change for millions of years. By that time any chemicals that make up the basic building blocks of
life may very well have been destroyed so the environment can change again to produce the new building blocks.
Unless of course a volcano emptied into a thermal vent while an ice block from space hit it the same time lighting struck the bottom of the ocean. I
guess, but that's still missing lots of things in my opinion.
