Regarding the first sentence, why must the various evolution theories keep changing after tests then?
1. when you do experiments, you learn more and you incorporate that data into your model
2. the things that "keep changing" are details concerning the mechanisms and processes. Obviously we don't know everything there is to know about biology, genetics, etc. If we did, we would have no need to train more biologists. But again, this is about
details. Nothing has changed in the big picture. Common ancestry and evolution as a result of descent with modification and natural selection. Not a single test or experiment or discovery has ever shed any doubt on that.
There is not other explanation that I've seen that explains the existence and complexity of life.
ID/creation, explains
nothing. It merely asserts, based on a 2500 year old religious story.
Evolution theory actually explains. Based on evidence. And testable predictions.
And the explanation needs to cover both to have any validity whatsoever.
"both"? Are you complaining now that evolution doesn't address the origins of life, but only the origins of diversity?
Well, tough luck. It is what it is. The origins of species and the origins of life itself, are two different questions.
It's just the way it is.
Life is here. It exists and we can study it.
We don't need to know how life itself came about, in order to study and unravel the processes that
existing life is subject to.
Nope. Again, creation explains
nothing.
Creation merely asserts. And it does so based on a 2500 year old religious text.
Of course, you may disagree. I give you permission.
It's not a matter of agreeing or disagreeing.
It's a matter of you just being plain wrong. It is not a matter of opinion.
It is a matter of fact and evidence.
"creation" is a religious assertion. Not a scientific explanation.
