"duh, of course the universe is tuned such that life can exist, if it *wasn't*, we wouldn't be here". - You forgot the part where it conflicts with anything I said. Yes, the universe is tuned for life. Now what fine-tuned it if not God?
Well, people have come up with a bunch of ideas over time [wikipedia.org]. Or maybe it's whoever who set up the simulation in which we live [simulation-argument.com], and maybe he/she/it/they live in another simulation, etc....
"The anthropic principle" is not a valid answer: it is an observation, not a cause.
lolwut? A complete lack of an answer. And if you don't want to search for or provide answers then get out of my scientific discussion.
A link to someone with an actual argument! If only you had formulated it and it wasn't based on erroneous assumptions I would be impressed. Here's why the argument doesn't stand: "the same non-random forces which propel biological evolution also propelled abiogenesis. Specifically, Natural Selection. " - Assumes that Natural Selection can drive evolution and abiogenesis. It cannot. "Natural selection is the gradual, non-random process by which biological traits become either more or less common in a population as a function of differential reproduction of their bearers." (Wikipedia, emphasis mine). In other words, Natural Selection takes helpful traits that already exist and spreads them. It does NOT create new traits. It CANNOT. Only random chance can create new traits when you deny intelligent intervention, and random chance isn't up to the job of generating life. "For example, the simplest theorized self-replicating peptide is only 32 amino acids long." To the best I can tell the peptide he's referring to is "A self-replicating peptide." which, while interesting, is not actually self replicating. It merely binds the two halves of itself together, so to replicate it must be supplied with a constant supply of duplicates of its halves. To replicate just once it needs 64 specified amino acids (iself and two halves), for the second generation it needs another 64 (four more halves) and so on. Interesting, but absolutely useless for the origin of life. No real self-replicating entity smaller than a cell has ever been discovered, and if it has it is no doubt much larger than 32 amino acids. So everything that rests on his 32-acid estimate is complete nonsense.
Assuming that he exists and is pissy about people not believing in him.
The evidence that he exists is precisely what I'm arguing, and "pissy" isn't exactly the right word here. More like righteous wrath. Say you created a robot and made it self-aware (That's not possible, but for the sake of analogy assume it is). Instead of being grateful and giving you a good name, it spits oil in your face and runs around doing evil. It denies your role in its creation, saying that it was inevitable. Now, if you truly love your creation like God loves us you'd allow it to have a second chance and return to being good, but if it refuses you'll destroy it before it can bring yet more shame upon you and do yet more evil. It's not that God gets "pissy," it's that we completely defy his purpose for us and thus we deserve to be destroyed.
Really? That's the best you've got? 'We exist and we came to exist by chance, therefore it's likely that we exist.' Presupposing your conclusion is bad form. It's also a logical fallacy.
And the evidence that it's "just not possible" is?
Ok, you asked for it. The simplest genome known today has 580000 base pairs. Assuming that the simplest possible genome is 1 percent of that (more accurate predictions run about 60-70 percent of that but I'm being very generous here), and assuming that generating a genome is synonymous with generating a cell which is a massive simplification in your favor, you still need to come up with genetic information with a probability of one in 4^5800. I have yet to find a calculator that gives a value for 4^58000 besides "Infinity" and "ERROR", the highest you can get in Google calculator is a mere 4^511, which is 10^307 in more common notation. In contrast the number of atoms in the earth is only about 10^50 and the number of seconds since the origin of the universe is about 10^17. Now you have some explaining to do. How do you overcome odds so great the almighty Google declares them infinite? Natural selection won't help you here, it can only account for the preservation of features that have already arisen, before the simplest cell arose it played no part in accelerating its creation. You have only random chance to lean on, and unless you claim that infinite universes exist which is a very unscientific claim, there's just no way life could arise by chance.
The definition of a scientific theory: "a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment"
Intelligent Design is a well-substantiated explanation of the inability of the natural world to create itself, based on a body of facts (such as those listed above but certainly not limited to them) that have been repeatedly confirmed through observation and experiment.
Evolution, on the other hand, is a poorly-defined conglomerate of Common Descent with Natural Selection that fails to provide any real evidence that the later caused the former.
You've seen just one of the data points I could bring to bear on the issue. Are you scared yet? Are you going to throw up a ridiculous denial? Are you going to just leave this thread and never return? Are you going to accept the truth? Or are you going to actually present real evidence? Of all those options, I find the last to be the least likely.
