What do you mean by "macro evolution"? The usual meaning I gather is the evolution of one species from another. While one of the biology dictionaries I have on my desk at work defines the term that way, the other (Henderson's) does not even list it.
Exactly what does the evolution of one species from another have to do with "beginnings", please? What is the connection, if any?
Evolution has been defined since the 1930s as the observed change in the frequency of alleles in a population of interbreeding organisms. Alleles are different varieties of a gene.
If and when there are enough of these changes in frequency, the organisms can no longer interbreed successfully. Two otherwise similar populations of organisms that cannot do this are generally regarded as different species by biologists. This has been observed in captive populations of fruit flies without direct human intervention, just genetic drift. It is also almost true of the north American hawthorn maggot fly which, in the wild, has almost but not quite diverged into two separate species since the apple was introduced to that continent in the early 1600s. Attempts to cross breed the apple variety and the hawthorn variety fail in 19 trials out of 20, on average.
Pointing out that the assertions, assumptions and muddle implicit or explicit in creationist talk about abiogenesis or evolution are false or irrational isn't always anger, it is usually a mere statement of fact, not different from pointing out that two times nine does not equal pumpkins.
