Ok the creationists TRY a come back and we get the first signs that this discussion is inevitably going nowhere.

Macro evolution, that is, the theory that all life on earth began from a primordial soup with amino acids in it

Macro evolution vs Micro evolution.
Micro evolution is normally defined as the shift due to selective pressure of a gene or group of genes in a population of living organisms.
Macro evolution is normally defined as the formation of new species or taxinomic groups due to selective pressure.
As I explained earlier and as a few of us have been at pains to point out evolutionary theory doesn't gives us much clue on how the whole thing got started, however creationists keep banging on the point claiming it a weak point to the theory it is not a part of.
Demonstrating macro-evolution runs into difficulties as there is no accepted concept of a species at current, however it is accepted in scientific circles that extending proof of micro-evolution to explain the diversity of life is the most parsimonious solution.

Btw Perth why the link to the Polish radio site?
On edit sorry defined micro evolution twice!! duh
