Wow...where to begin. How about here...
“In the eukaryotic fossil record, sexual reproduction first appeared by [1.2 billion] years ago in the Proterozoic Eon.[49]K”
How does one really know this to be true? Do you? It is my opinion that this is only someone’s opinion, because it can neither be proved or disproved, can it? It is no different than someone stating that 1.2 billion years ago there was a dog living in what is now Seattle. No one in their right mind would state with certitude that that was the case, because it cannot be proved. Opinion? Sure. Conjecture? Why not? But certitude?
The problem with evolutionist hypotheses is that an evolutionist tries to come up with said hypotheses in order to explain how we got here. Hypotheses like the one above are, in my opinion, silly and specious at best. This is why I am challenging evolutionists to answer the questions on considertheprobabilities.com. (By the way, no one has been able to answer any of the questions so far.)
If I find a rock at the bottom of the hill, with crushed grass in a trail behind it, I might conclude that it rolled down the hill. But that would just be my opinion, of course, because no one saw it roll and I can't "prove" it. Maybe it was ejected from a volcano in Italy, orbited twice around the Earth, and fell in the spot I now see it. By your standard, there would be no difference between the two conjectures.

Yeah. That's what scientists do. They observe something (we are here; there's a rock at the bottom of this hill) and try to come up with hypotheses to explain it. If you don't like science, just say so.

Fortunately, the advancement of science does not depend on your opinion of it.
