As I mentioned earlier, we are talking about science, so I hope that you are getting your scientific information from reputable sources. So quoting your source will help convince me and other readers that you have credible data.
In addition, I am working hard to debate with you personally, so it's laziness on your part to paste other people's argument wholesale without even analyzing them.
Ibram Gaunt has already written well on the importance of evolutionary biology to science (see above).
I know you will not be convinced by whatever evidence I present here, but for the benefit of other readers I shall try to address your (actually other people's) criticisms.
1. Evolution is untestable? False.
J B Haldane once said that if you can find rabbit fossils in the Precambrian, it will help refute evolution. None have been found.
In addition to fossil evidence, modern genetics experiments also overwhelmingly support evolution. I have already mentioned experiments on flies, butterflies and chick that test evolutionary theory. Other models include zebrafish and mouse.
2. Irreducible complexity is pure bunk. Paley's brass watch and Behe's mousetrap are both terrible analogies of living systems. I have written a criticism of their analogies in this article.
http://freshbrainz.blogspot.com/2006/10/irreducible-complexity-pwned.html3. The "increase in information" angle comes from Bill Dembski. In reality, new information enters genomes all the time. I have already mentioned polyploidy in plants. In addition to whole genome multiplications there are additional chromosomes, gene multiplications, lengthened genes, truncated genes, modified genes...many modes of increasing information.
4. Fossilization of organisms is rare, so it is unreasonable to expect all the transitory forms to be recorded in fossils. Palaeontologists can find dozens of transitory fossils per genus, but creationists are never satisfied. Do you know why?
If they can find one million transitory fossils, creationists will demand 2 million. If they can find 2 million, creationists will want 4 million. Where scientists build evidence, creationists always see gaps.
5. Abiogenesis is not part of evolutionary biology, and personally I think it is not as strongly supported as evolution. Still I should remind you that the definition of life (as an emergent trait) has always been controversial.
People (vitalists) once considered sub-cellular components such as "organic" chemicals (eg. urea) as alive. Today we can synthesize them chemically, so we don't consider them alive.
Since cells are made of non-living parts, how can cells be alive? We just accept this. So if it is easy to imagine life emerging from non-life spatially, we can also imagine life emerging from non-life in time.
Anyway even if life has always existed, it would not support special creation. In fact it would refute creationism, since life has always existed it would by definition not require any sort of creator.
6. Biological evolution is a non-random process, because it acts via natural selection. Also, since genes have organization, sequence changes can produce predictable effects.
Also, very low probability events are inevitable at evolutionary (geological) time scales.
As for that extra arm you were waiting for... someone someday will eventually sprout an extra arm.
http://abcnews.go.com/Health/story?id=2021142&page=17. "Microevolution" is just the creationist excuse to have their cake and eat it too. They know that bacteria and viruses mutate rapidly and display wildly different characteristics such as virulent, host jumping and multidrug resistance. So they say that microevolution can only occur below the species level.
But here's the trick: they don't accept the scientific definition of species (reproductive isolation) and use their own definition called "kinds". So no matter how much the descendant populations diverge they are still the same kind.
Using this word game no organism can ever evolve beyond the "kind" level! Monkeys evolving into other monkey species are still monkeys - only microevolution!
In reality there is no such barrier to evolution. Every speciation step is of course at the species level, but it does not magically stop at that level. Life continued to evolve until we have the full biodiversity we see today.
8. You say that since no human was around to record exactly what happened during the inception of life, everyone is only guessing and the origins must be taken on faith.
If all criminal investigators believe that, then murderers will never be convicted, because many murders occur without anyone else around. Also the data is usually incomplete. Even if caught on camera, video cameras have a 1/20 second gap between frames.
Yet the bloody shoe prints, knife in the sink with suspect's fingerprints and victim's blood, absence from usual routine during time of crime... various evidence using different approaches, demonstrate beyond reasonable doubt that the suspect is guilty.
Faith is not used to determine the truth here.
So why do you insist on using faith to refute something which already has so much supporting evidence???
