1.How did life with specifications for hundreds of proteins originate just by chemistry without intelligent design?
By chemical evolution involving natural selection for function.
2.How did the DNA code originate?
As above. (1)
3.How could copying errors (mutations) create 3 billion letters of DNA instructions to change a microbe into a microbiologist?
With the help of natural selection, drift, and niche filling. Being a microbiologist is filling a very specific niche.
4.Why is natural selection taught as ‘evolution’ as if it explains the origin of the diversity of life?
It's not. It's taught as one of the major processes that contributes to the evolution of the diversity of life.
5.How did new biochemical pathways, which involve multiple enzymes working together in sequence, originate?
Mainly by mutation and selection.
6.Living things look like they were designed, so how do evolutionists know that they were not designed?
They don't look
intelligently designed when examined carefully, and evolutionary biologists know they're not
intelligently designed because they have examined them carefully.
7.How did multi-cellular life originate?
By single celled organisms forming into colonies, and then reproducing together.
8.How did sex originate?
Through intelligent design by a voyeur? (There are various hypotheses, but we don't know exactly how yet).
9.Why are the (expected) countless millions of transitional fossils missing?
Who expected which fossils to be discovered when? In a non-evolutionary world, there should be no transitionals. The transitions in form that we have discovered confirm that our biosphere is evolutionary.
10.How do ‘living fossils’ remain unchanged over supposed hundreds of millions of years?
They don't. "Similar" doesn't mean unchanged.
11.How did blind chemistry create mind/intelligence, meaning, altruism and morality?
Intelligence and altruism are produced by variation and selection, particularly in social animals. It might be worth noting when you ask that question that the origin of intelligence cannot be explained by intelligence. Morality and meaning are subjective human constructs, and only created indirectly by blind chemistry in that it created us.
12.Why is evolutionary ‘just-so’ story-telling tolerated as ‘science’?
It isn't. Hypothetical scenarios to illustrate how evolution can happen are sometimes used in science
teaching.
13.Where are the scientific breakthroughs due to evolution?
In our ever increasing understanding of the biosphere, present and past.
14.Why is evolution, a theory about history, taught as if it is the same as the operational science?
It isn't.
15.Why is a fundamentally religious idea, a dogmatic belief system that fails to explain the evidence, taught in science classes?
Creationism
isn't taught in most science classes.
