1- No that is you OPINION of what he was talking about and as we have already determined you have no science background and just an agenda so your opinion is highly biased.
It is categorically not my opinion that he said the following (emphasis Sapiens'):
"Well, it could come about in the following way: it could be that at some earlier time, somewhere in the universe, a civilization evolved by probably some kind of Darwinian means to a very, very high level of technology, and designed a form of life that they seeded onto, perhaps, this planet. Now that is a possibility, and an intriguing possibility. And I suppose it's possible that you might find evidence for that if you look at the details of our chemistry, molecular biology, you might find a signature of some sort of designer, and that designer could well be a higher intelligence from elsewhere in the universe.
But that higher intelligence would itself have had to have come about by some explicable, or ultimately explicable, process. It couldn't have just jumped into existence spontaneously. That's the point."
This is not a simple matter of opinion. His words are there. Do you deny them?
2- There is no theory of evolution that encompasses all theories,. That is called the science of evolution. There is a theory of evolution through natural selection and various other mechanisms all of which make up that science. Those are the "processes" that you are quoting. Unless you understand all the theories you are just repeating what you learned in school which is a very very limited view of the science of evolution.
Again, you're spouting nonsense. There is a singular THEORY of evolution which encompasses the variable explanations and mechanisms that are proposed to explain evolution. All of the things you quoted are various mechanisms and subjects WITHIN evolutionary theory - except for a couple, which were competing hypotheses. The theory of evolution is a broad explanatory framework encompassing a variety of fields of study, competing hypotheses and explanations. This is not difficult to understand.
