All I can see is that they are roughly spherical and grouping together. And though they have not solved enough of the problems of abiogenesis they have solved quite a few of them. You have to understand that we could not really form a theory on abiogenesis until sometime after we had a full understanding of how the cell works in the first place. Otherwise all that they would have is guesswork.
Yeah I agree I don't know how they come to the conclusion. I felt it was a fairly trivial point so I didn't do a lot of reading on it, but every source said the same thing. Not on creationist websites by the way ha ha.
As far as Adam and Eve, I am not a literalist with regard to the creation events as recorded in the bible. In addition, my non-belief in evolution is not because I think theistic evolution couldn't have happened. On the contrary, I think there is some fairly compelling scriptural evidence for it.
I just don't think the numbers could possibly add up.
In a recent study for example, they determined, with fairly liberal hedging in fact, that a single point mutation required to evolve one functional protein into another very closely related protein would take 5950 years on average. The second point mutation at the same point or within range of the same point to induce the same change in the protein would take over 100,000 years. The third would take longer than the earth has been here. They calculated it would take at least four point mutations to complete the evolution of that single protein. Couldn't happen.
This is for one protein to evolve to very similar protein in the same family.
How many actual morphological differences are there between chimpanzees and humans? How many mutations to effect even one change? Because most take at least 4 to 7 point changes. And the old "we share 99.6% of our DNA" is a flat falsehood. It's like the "if a thousand monkeys on a thousand typewriters typed for a thousand years they would turn out the works of Shakespeare". The truth is they wouldn't put together a single seven letter word between all of them.
So how many differences? A hundred? A thousand? Five thousand?
There are other significant logical problems. You can say it's an argument from incredulity if you want, but I think,it's a bit more evidentiary than that. I just can't buy it, and the proponents lie too much, like the monkey thing for example. None of what I learned in high school evolution chapters is true today. That's a problem, because that means everything they said 40 years ago when I graduated was not true, but I'm supposed to believe everything they say now?? Can't do it.
This complexity problem is a real problem for evolutionists. It isn't going away. It is going to get worse. No doubt about it.
Back to Adam and Eve; however it happened, I believe that they were real people and that they were part of a real drama that really happened. The exact circumstances? I don't know, and I don't think that's the point of the account.
You have heard that mitochondrial Eve and chromosomal Adam have been calculated to have possibly lived at the same time? Ha ha I just laughed at that.
