First I'm going to analyze the original post here quoted and clear several things up:
Shermana wrote:Well if you're not gonna debate Cyanobacteria, then kindly retract your claim that Genesis would be 0% reliable. Say that it's possibly reliable involving the order of plants first, sun second.
Are you aware that Genesis states plants first, sun second? That might clear up the confusion.
None of these arguments are non-sequitur.
Here I detect the first, fatal flaw. Either you're making a logical
non sequitur between using cyanobacteria and plants as examples, or you have deeply confused two
entirely different kinds of organisms.
Cyanobacteria form part of the domain
Bacteria, and as such are prokaryote organisms - without a nucleus.
Plants (strictu senso), green plants, Viridiplantae are a kingdom within the domain
Eukaryota, so they're eukaryotes.
This is a non-trivial difference
Also, there could be no plants without a Sun, either, since the Earth was formed after the Sun. This is well-known in astrophysics and geology.
This article does a good job at it.
As well, plants are autotroph photosynthetic organisms which need the Sun to make their own organic matter, without it, they'd die out. This is well-known in biology, check the
chemical process.

I'm sorry that I like adequately responding in the adequate sections, it's some weird mania I have.
Shermana wrote:Basically, there could be no such thing as plants before an ozone layer. Impossible.
This is true. But it's as true that this is a strawman or a
non sequitur, since plants are not cyanobacteria. More on this later.
Shermana wrote:Thus, Genesis Creationism is by default correct.
That would be evidence of "God".
If you don't accept this argument as valid, that's your problem.
I think a post I did already covers this:
Ragna wrote:There's not a dichotomy between "current scientific theory" and "creationism". For Biblical creationism to be true, we would need another world (one with a sea above the atmosphere, to begin with). Therefore, creationism is not a scientific position.
Now with the debate:
OP wrote:Questions for debate:
1. Is this argument valid, constituting evidence?
It's simply fallacious reasoning and bare statements, so it's not proof (and it presents no evidence to back up anything, either).
OP wrote:2. Which came first, plants or the Sun?
See this article:
http://en.wikipedia.org/wiki/Formation_ ... #Formation
The Sun came first and then matter formed the planets which revolve around it. This is the commonly accepted scientific knowledge about it.
Life on Earth is more or less as old as
3.8 billion years. Cyanobacteria are pretty old, and once the
oxygen catastrophe happened, aerobic life could freely evolve. The ozone layer could arise spontaneously after there was free O
2 in the atmosphere via
ozone-oxygen cycle.
Since prokaryotes predate eukaryotes and largely multicellular eukaryotes, when the plants
firstly appeared about 520 m.a. ago, there was already an ozone layer available.
OP wrote:3. Can cyanobacteria survive without an ozone layer?
I don't know whether they can now, but before there was an ozone layer they most probably could.
Wikipedia wrote:Evolution of early reproductive proteins and enzymes is attributed in modern models of evolutionary theory to ultraviolet light. UVB light causes thymine base pairs next to each other in genetic sequences to bond together into thymine dimers, a disruption in the strand that reproductive enzymes cannot copy (see picture above). This leads to frameshifting during genetic replication and protein synthesis, usually killing the organism. As early prokaryotes began to approach the surface of the ancient oceans, before the protective ozone layer had formed, blocking out most wavelengths of UV light, they almost invariably died out. The few that survived had developed enzymes that verified the genetic material and broke up thymine dimer bonds, known as base excision repair enzymes.
Many enzymes and proteins involved in modern mitosis and meiosis are similar to excision repair enzymes, and are believed to be evolved modifications of the enzymes originally used to overcome UV light.[56]
Firstly, life started in very simple forms; the firsts forms ought to be much more simpler than even modern prokaryotic cells. There are organisms today (extremophiles) which can withstand the most extreme conditions, and so there's no reason to think that the ancient environment was necessarily
lethal to primitive cyanobacteria which lived
deep in the ocean (and all this assuming the UV radiation emitted was in fact the same back then, which I don't know).
OP wrote:4. Does this prove Genesis being accurate?
At all, as I've already pointed out, an entire new world would be needed for Genesis to be accurate (see Gen 1:7). And anyway nothing else than proving Genesis accurate proves Genesis accurate. A criticism like this does not stand, since it simply consists in inaccurate and raw assertions about astrophysics and biology.
Now I demand biological and geological support that the Earth formed before its star. A millennia-old book is not.
