I don't think that's the argument. I think the argument is that DNA is too complex to have happened by chance or random occurrence. A computer is complex and there's relatively few people in the world who know and can understand all the elements of electricity, electronics, computer theory, magnetics, and all of the processes that go into a computer...yet nobody claims that computers just randomly evolved from lightning bolts.
I think the argument is that DNA is too complex to have happened by chance or random occurrence.What is the evidence of this? Individual Hydrogen atoms are extremely complex too. So lets say you assume Hydrogen atoms and protons, and quarks are designed as well -- at what point does one then believe that physical laws no longer apply and an Intelligent Designer has control over everything? Wouldn't it make sense for us measly humans to try and figure out how this stuff works instead of just throwing up our hands and giving up?
Actually, that's what non-ID evolutionists must believe, since they don't consider the possibility of a Creator; hence everything happens just because.
You see, you'll be told you're guilty of making the strawman appeal to incredulity. Just because its mind-bogglingly complex or so improbable means it can't be that way by chance.
Biological organisms are much different though. Despite the greater the improbability of any arbitrary biological process, the fact that it actually exists means the possibility of it being is 100%. In fact with the natural order of things, the way they are is just the most likely way for them to be. The physical constants of the universe having to be each as precise as they are - both individually and in concert - each dependent upon all the others for their specific values, and the incomprehensible harmony of the mechanics of the universe is not collossally improbable, that's just the natural tendancy of the universe. Why argue about the seemingly improbable odds of left-handed proteins being required for all life, when identical but right-handed (chimeric) proteins would destroy the life being randomly assembled, the fact that it is that way shows that's the universes natural tendancy in being. Over the time of billions and billions of years, the natural tendancy would be for more left-handed proteins to assemble themselves, so obviously all biological process are going to be dependent on them. That's just pure logic. Why debate or argue about that? This is not a matter of faith or anything. It just is that way. Period. Creationists will tell you that God just is, so why can't evolutionists just have their is too?
Look, flipping a nickle 1000 times in a row and coming up heads is monumentally improbable, but if it happens then the possibility of that happening is 100%. Now for that to happen again would be even more remote of a probability, but if it does happen again, the possibility of it happening again would be 100%. Just because each of the components and physical constants of the universe in and of themselves have a higly improbable likelyhood of occuring, the fact they they all did simultaneously assemeble together into this universe means that the possibility of a universe constructed in the way it is is 100%.
Please state the maximum complexity which can occur randomly and give your sources.
BTW, random variation is part of evolution, but so is natural selection. The joint operation of both is a convergence upon adaptation to current conditions. This joint operation of both is not random.
Unless they were lightning bolts coming out from from Bill Gates' rear-end...
