According to them, there have been countless cat-dog remains found strewn all throughout history.
Haven't you heard?
Both cats and dog are part of the Carnivora order and the common ancestor would have existed before the distinct traits we call feline or canine developed, so it has never been an assertion that something like a modern cat rabidly developed into a modern dog.
Aside from the underlying structural patterns in cats and dogs that indicate a distant relationship the best evidence is the pattern of genetics.
Another good example of this kind of thing is the Tasmanian wolf, Thylacine.
You can see here that while its shape, size and ecological niche was pretty similar to a coyote if you examine its genetics or bone structure its much more similar to a kangaroo than it is to a wolf.
(In fact a wolf is more similar to a human genetically than it is to a Thylacine).
Evolution has an explanation for these patterns... I have not seen a consistent or coherent alternative.
Are you sure there is a distinction between an ' alive"
chemical or its reactions, and one that is not?
That's one of the problems with the discussions of the beginning of life... there really isn't a clear border. At the smallest scale the chemistry of life is identical to the chemistry of non life, it's the greater pattern that's interesting.
Proof in the mathematical or philosophical sense? No.
Proof in the "beyond reasonable doubt" sense? It absolutely has proof.
Jesus, God Incarnate, aLREADY DISPROVED IT!
How?
You should know that sincere Christians disagree about many details of your religion. One of those disagreements is with how poetic and allegorical the Book of Genesis is.
Where has macro evolution ever happened?
The easiest to quickly visually demonstrate and most significant to the YEC narrative is the variation of primates from a common chimp like ancestor to modern chimps, modern humans and a whole mess of extinct variations.
