Goku: As Keysi alluded to most 'aliens' would be single celled type organisms, and for the most part what these aliens would be like is largely speculation. The humanoid aliens in pop culture is a side effect of human psychology being self-centered and subconsciously imagining that if aliens exist they must look like us. We do this to animals too in many cartoons; we modify the animal to have a humanoid look.
Yes humans do this when they commit anthropomorphism and anthropopathism, we also innately recognise patterns (paradeolia). Also another thing to consider is sleep paralysis. In other words Goku, we didn't really need to be told bears shi* in the woods because we know of all of the things that surround such claims. We here all will likely know the chances of aliens visiting us are zero because they highly likely don't exist. We also have to consider what Einstein said about increasing mass infinitely beyond the speed of light, etc...
But one thing about your post I would mention is that obviously Keysi might be tempted into thinking everything you said is plausible, when in reality it's obvious that with all of the chicken-and-egg scenarios in nature, and within the cell for example, you simply aren't going to get anything useful. Even if you could somehow create a protein because homo-chiral amino acids occurred by a meteor which is preposterously simplistic thinking in comparison to the sophistication of the cell, we also have to consider the now thousands of experiments performed in an attempt to "repeat" as it where, the conditions of life coming from non-life. All of that data counts as evidence against life creating itself, when we think how able scientists are to manipulate all kinds of conditions. By now they would have come up with something, if they are intelligent, knowledgeable manipulators, whereas chance-happenings on planets, are not deliberate attempts to create life. An agent deliberately designing something, gives a far, far greater chance of something being designed than random chance, and I don't believe you truly are an idiot that doesn't know the difference, for I don't recall you ever arguing that a sand castle was created by wind and wave. So then it is is special pleading to claim chance abiogenesis would stand a better chance of creating a sophisticated, designed cell, than some random assembling which is accidental and therefore wouldn't have any goal to design anything. (please tell me you understand 2 add 2, and therefore there is hope for you?)
So while I said we can take evolution for granted in this thread, that is fine, but I don't think that can go as far as making 100% speculation seem like it is science fact, and I find in most articles about alien life on the net, that is the problem, they treat it as though many billions of planets is all you need to get life.
By analogy imagine an abandoned factory for china, where there are 10 million teapots and china sets, would we now argue that it is inevitable that because there are so many of them, that surely one of the cups must be filled with tea or coffee?
This is an illusion, because intelligent designers get you tea. So with your homo-chirality example, I could argue that tea somehow got made if some water was spilled by accident into a cup that happened to have a teabag in it. Who knows, perhaps the milk and sugar was then added by some other accident. Just mentally conjuring scenarios like this, doesn't mean this is how tea and coffee occur. Just making these scenarios SOUND like scientific fact, won't mean they are. For example what force created the tea-bag? Oh well here we go again with a science-SOUNDING story, perhaps the bag with the tea-leaves in it, only has tea-leaves because all the loose leaves blew away in the breeze leaving them left in the bag, then the bag somehow sealed itself. This is what the majority of scientists likely accept as some sort of scenario!
(see, not even CLOSE to clever, because they basically leave out plausibility, and treat it as though it is a magic-evolution, which happens no matter what the facts show to the contrary.)
This post is for Keysi, I just don't want him to be fooled into thinking that the problem of abiogenesis is solved, when all of the science so far, inductively, all of the evidence - points to life not being able to form naturally. So please don't use this thread as a launch pad for preaching your ideology, Goku, by inserting claims that abiogenesis is some simple problem we can overlook. LOL
Moreover, the amino acids produced were in any case what is known as a racemic (50:50) mixture of left and right-handed forms, whereas all living plants and animals can only use left-handed amino acids to make proteins. (Left and right hand refers to the fact that the amino acids, though chemically identical in their ability to form peptides, are mirror images of one another, like our left and right hands. An exception is the simplest amino acid, glycine.) If amino acids of the wrong type are included in the chain during manufacture, life’s proteins cannot fold properly into the shapes needed to function. Life therefore requires what is known as an ‘optically pure’ supply of solely left-handed amino acids, whereas chemistry by itself, following the laws of chance, will always produce a racemic mixture. Moreover, all sugars in DNA and RNA must be ‘right-handed’, otherwise the vital informational double helix could not form.6
Ken says, “Evolutionists argue that given sufficient time proteins could form by chance. But, for a protein of just the minimum 100 amino acids (many are tens of thousands long), for all to be left-handed, and assuming that it did not matter which order they appeared in, it’s like flipping a coin 100 times and resulting in all heads. The number is astronomical.”
Indeed so—it is one chance in about 1030.7,8 Numbers like this are too hard to imagine. So one comparison used by CMI speakers is guessing a 30-digit PIN correctly first time.9
The ‘primordial soup’ chemical synthesis of functional proteins and enzymes by chance is not plausible when the uniqueness of God’s special creation is examined.
But in fact, the order is crucial at most positions in the chain, and for each position chance has to choose from 20 amino acids, which makes the problem stupendously greater. In all proteins, the order is crucial, some more than others. E.g. calmodulin, the ubiquitous calcium-binding protein, has almost all of its 140–150 amino acids ‘conserved’ (the same in all organisms). So if we generously (to the evolutionists) assume we have a pool of 20 left-handed amino acids, the chances of all 140 amino acids to be right is about one chance in 10182—like guessing a 182-digit PIN.8 And all one would have, even then, is a lonely protein, useless without all sorts of other proteins and other machinery of life
No offense to Goku, Keysi. As an amateur with some basic science background he isn't a stupid man I will concede, but you have to beware of the fact that this is someone who swallows any argument that will favour life coming about on it's own and sometimes I have noticed that he will hear something like the meteor example but will not search out all of the problems. I have noticed this many times now, he will stick to a story he has been told of how evolution could have happened, some speculative story telling about how a problem can be solved, then he will tend to biasedly treat that story as though it is factual truth and ignore any problems with that story. It doesn't seem scientific to me, to treat RANCID SPECULATION as fact.
Saying meteors can strike earth and arrange folding proteins somehow, is like saying you can throw stones at a soft-rock house and eventually it will turn into Michaelangelo's David.
(In other words, Goku hasn't appreciated just how specifically complex, life is. (specified complexity). In actual fact a cell must have DNA to code the protein and the DNA must have the protein, there are also enzymes and guiding chaparone proteins etc...there is nothing in nature which can create a cell, as science has shown. Hundreds of billions of planets won't provide a design for the cell, all of the designer features in a cell, according to inductive logic, are backed by 100% of the data which shows that such sophisticated features only come from designers. What are those features life is over-qualified in? Specified complexity, contingency planning, information (no code ever known to be created without intelligence), correct materials, goals, viability, clever solutions to obscure, unique problems, etc...
