What evidence do you cite that modern Cyanobacteria are not as simple as they were 3.5 billion years ago?
So? We have life with complex features that lose those features as well.
Life has always existed.Um... unless you are suggesting life has always existed,
Again...So?The complexity ratchet does go back a little bit, but only so far. In the cases I know of, it requires a commensal relationship with a more complex species.
Fine. So where is the evidence that the first cell is incredibly simple? We have a relative complex life form in Cyanobacteria at 3.5 billion years ago. There is no evidence of the first cell, we have no comparison for the life forms we do have evidence for so I hope you will concede that there is no evidence that the first cell had to be incredibly simple. We have no idea other than it being perhaps somewhat simpler than the fossilized Cyanobacteria which is not informative about what came before or how complex it was.I am citing the observation of the simplest life we know of as the first fossils as evidence that life started simply and evolved complexity over time. Since we don't have the genomes of those ancient genomes, we can't use that as evidence one way or the other.
Again...So?

I disagree. It has been shown that as early as 3.5 billion years ago we had a fairly complex life form and then we have no gradual rise of complexity but an explosion of complexity around 542 million years ago.Already given multiple times.

Even if they were simpler than today's we still have the situation of there being no gradual complexity arising in the fossil record but the sudden appearance of it 542 million years ago.Please show that the cyanobacteria 3.5 billion years ago were complex.
So I assume I am on this posters ignore list...this might be fun. evil grinSo hey, just out of interest, did you know the new ignore feature completely removes posts from people you're ignoring? You don't even get a place holder "this poster is on your ignore list" post. Just nothing! It's pretty cool.

That is the evidence.How did you determine that they suddenly appeared?
Correct.If God can be defined as "alive" then Christians believe that life has always existed.
there is no "understanding" about how life got here.Life arose by abiogenesis, which is a completely separate field to evolution. Evolution may, in fact, be utterly wrong, but that doesn't affect the understanding of how life arose.
you are forgetting what maynard says.2. As creatures evolve, they tend to get more and more complex, so extrapolating backwards, at some point they must have been considerably more simple.
As for modern mono-cellular life being complex, well, yeah. As Thunderf00t so excellently put it, "What you are looking at is the most successful organism on earth; a grizzled heavyweight champion of evolution." Modern mono-cellular eukaryotes are often very complex organisms. There is simply no reason to believe the earliest life forms were anything like that.
We're specifically talking about cellular life. I don't believe anyone has ever seriously claimed that God is composed of protoplasm.If God can be defined as "alive" then Christians believe that life has always existed.
Try ectoplasm.We're specifically talking about cellular life. I don't believe anyone has ever seriously claimed that God is composed of protoplasm.
