Wrong again. The theory of universal common ancestry states that all life is descended from one single common ancestor.

Abiogenesis = a hypothesis about how life could come about through physical means.

Universal Common Ancestry = a theory to explain how all known life shares features of common ancestry.

Evolution = a theory about how life changes in response to selective pressure upon genetic variations within a population.

For the typical Creation story to be true - all terrestrial life had to have come from those few species that could fit on a boat of known dimensions. This entails semi-universal common ancestry between “kinds”, and speciation and evolution at a rate far beyond that proposed by evolutionary biology.

So the difference seems to be that creationists accept evolution so long as you don't call it evolution, they accept speciation and common descent - but only within a non defined “kind” - and at a very rapid rate.

Do you think mice and rats are the same “kind”?

Are tigers and lions the same “kind” or a different “kind”?

Are old world vultures and new world vultures the same “kind”?

The Animal …Kingdom
sharing with all other members of this group the need to feed on organic matter (unlike plants which can create energy using light and minerals)

The Chordate (or vertebrate) … Phylum
sharing with all other members of this group of animals, a back bone with a hollow nerve chord

The Mammal … Class
sharing with all other members of this group of vertebrates, the ability to feed their offspring on milk and having a body covering which includes fur

The Primate … Order
Sharing with all other members of this group of mammals, a thumb that can be opposed to the other digits, binocular vision and various more broadly defined characteristics (including high intelligence, relatively long maturation period for the young, dental similarities, tendency for complex social organization, and generally bearing one or two young)

The Lemuridae … Family
Sharing with other members of this group of primates, a slightly longer nose, smaller brain, long slender limbs, a tail, more specific dental features including the grooming comb formed by the lower incisor and canine teeth

The Lemur … Genus
Sharing with other members of this group of lemurs, scent marking methods, vocalizations, aspects of social structure and overall body shape

The Ring-tailed Lemur … Species

You are the one who is wrong. Without universal common ancestry the entire theory of evolution falls apart. If all species are not descended from one common ancestor then why would we assume that any species are? When you take away the false premise of this assumption all the rest of the assumptions of the theory of evolution fall away as well. The evidence shows that life changes and adapts, but it does not show that one species evolves into another species.

This is not what you just said.
