Barbarian observes:
Since speciation has been directly observed (even the Institute for Creation Resesarch and Answers in Genesis have admitted that) and since a change in allele frequency is always being observed, both microevolution and macroevolution are observed facts.
Can't get better than that.
Oh, I believe it can if you quit with the mumbo-jumbo and speak it like you really understand what it is trying to say.
One of the reasons you're having such trouble, is that even elementary science concepts are all "mumbo-jumbo" to you.
Barbarian observes:
The question of common descent is testable by DNA analysis, by predicted transitional forms later discovered, and various other lines of evidence. Predictions of the theory have always been validated.
Part of the confusion comes in the misunderstanding of what "theory" means. Newton referred to his "theory of gravitation" even though gravity was an obvious fact. A theory, in science, refers to something that has so much evidence supporting it that there is no reasonable argument against it.
Yep. Common descent is testable by looking at the DNA evidence. And we know it works, since it can be checked by testing it on organisms of known descent.
Yep. Even honest creationists admit, for example, that the numerous transitional forms are powerful evidence for evolution.
Yep. Repeated predictions of the theory have been confirmed. Would you like some more examples?
Then why is it still a theory
Because it's been repeatedly validated by confirmed predictions. Perhaps you don't know what "theory" means. It's has confident as one can be about nature.
Evolution is an observed fact. Evolutionary theory is the explanation for it.
Could it be there really isn't any concrete proof
Logical certainty is never part of science. "Proof"is only possible when we make the rules and deduce the particulars from the rules. In science, we observe the particulars and infer the rules from the evidence. Hence, Newton described his theory of gravity, even though gravity is like evolution an observed fact.
but rather, continued speculation __ conjecture at best with a hope of invalidating God, the creator of all the material placed in your hand for, "testing"?
A common misconception among uneducated creationists. In fact, science couldn't even in principle, deny the existence of God. It is limited only to the physical universe, and can say nothing at all about the supernatural.
You're letting your own fantasies disturb you.
