Anthony Edgar:
For example, the big issues in evolutionary biology (aka atheist theology) revolve around ideas of speciation - that can't be tested, so there's no way of being certain about of any of it.In early November I posted the following. You never addressed it but started making the same spurious claims again.
Macroevolutionary predictions serve only to support macroevolution theory (ie, atheist theology), but otherwise have no use in the real world.

So, if I understand you accept microevolution as a fact but reject macroevolution. What do you think the difference is? Is it based on the notion of species as kinds? See below.
Wiki provides the following references regarding examples of speciation from its article on macroevolution. Each is available by copying and pasting the title is a search engine:

As to the difference between microevolution and macroevolution, from wiki article on speciation:
One of the most important tenets of the theory forged during the Evolutionary Synthesis of the 1930s and 1940s was that "macroevolutionary" differences among organisms - those that distinguish higher taxa - arise from the accumulation of the same kinds of genetic differences that are found within species. Opponents of this point of view believed that "macroevolution" is qualitatively different from "microevolution" within species, and is based on a totally different kind of genetic and developmental patterning... Genetic studies of species differences have decisively disproved [this] claim. Differences between species in morphology, behavior, and the processes that underlie reproductive isolation all have the same genetic properties as variation within species: they occupy consistent chromosomal positions, they may be polygenic or based on few genes, they may display additive, dominant, or epistatic effects, and they can in some instances be traced to specifiable differences in proteins or DNA nucleotide sequences. The degree of reproductive isolation between populations, whether prezygotic or postzygotic, varies from little or none to complete. Thus, reproductive isolation, like the divergence of any other character, evolves in most cases by the gradual substitution of alleles in populations.
— Douglas Futuyma, "Evolutionary Biology" (1998)
In other words, if you accept microevolution then you accept macroevolution. As noted in the same article:
Nicholas Matzke and Paul R. Gross have accused creationists of using "strategically elastic" definitions of micro- and macroevolution when discussing the topic.The actual definition of macroevolution accepted by the vast majority of[24] scientists is "any change at the species level or above" (phyla, group, etc.) and microevolution is "any change below the level of species." Matzke and Gross state that many creationist critics define macroevolution as something that cannot be attained, as these critics dismiss any observed evolutionary change as "just microevolution".
If you are going to dispute scientific claims you must do so using the language of those claims.
