Appeal number 1,556 for you to please demonstrate that there is "purpose" in living forms, or even to explain what you mean.

Hi Brianna,
This is an excellent question and i'll try to answer as generally as
possible, you'll undoubtedly come across some exceptions to what I am about
to describe, but on the whole this is a good place to start.
Cells ... why ?
The purpose of a cell is to carry out a specific function through
interactions with its environment for the purposes of maintaining the
organism. In the case of single celled organisms such as amoebae or
bacteria, the cell is the organism and as such the cell/organism does all
the functions required for the life of the organism, e.g. eating, moving,
reproduction.
In the case of multicellular organisms, such as human beings, cells are
often specialized to carry out specific functions, e.g. nerve cells carry
electrical impulses around the body, muscle cells contract under
excitation, intestinal cells absorb nutrients from the digestive tract, red
blood cells carry oxygen to cells throughout the body, etc. In the case of
the human being there are thousands of specialized cells (properly called
differentiated cells) which carry out a function essential to the whole
organism. However, each of these cells themselves are also, in some sense,
an organism, they can be taken out of the body and grown outside the human
being and studied. These in vitro cells are often so specialized that they
carry out their specified function outside the body, but they do retain the
ability to move, eat and multiply (although in some cells this ability has
been turned off in the body).
So cells are biological units that can eat, move and reproduce. In single
cell organisms the single cell carries out all the functions requires to
keep the organism living. In multicellular organisms, the individual cells
can eat, move and reproduce, but they have a specialized function important
for keeping whole organism alive.
Mitosis ... what is it ?
Cells, as I described above, reproduce as a matter of survival, not of the
organism but of the genes that the organism carries. Again, in single
celled organisms, the reproduction gives rise to two new organisms. In the
case of the multicellular organism, mitosis gives rise to two new cells,
each capable of performing a new function within the organism.
Mitosis is carried out in cells which have nuclei (some cells do not have
nuclei ... another complicated question !!!). Mitosis follows replication,
in which the genetic material of the cell is replicated - two copies are
made, and represents the process in which 1) the copies of the genetic
material are separated and taken to opposite ends of the cell and 2) the
cell volume is divided into two new cells such that each contains one copy
of the genetic material. This process thereby has created two equal cells,
each with the same genetic material.
Thus, mitosis is the process by which individual cells divide. This
division is important is maintaining the cells in your body since
sometimes they get old and can no longer perform their specialized
function. Sometimes, however, the division can become uncontrolled,
nobody exactly knows why, but in the body such uncontrolled mitosis is
called cancer.

That is just a cell's purpose. The inner workings of the cell has many many molecular machines that have purpose for the cell's purposes.
Okay, firstly, not only is this as clear an example of
HARKing as I've ever seen (the predictions came
after the results were known in every case I am aware of), but it's missing an important step: the null hypothesis. What would we predict if organisms were
not designed? What predictions can we make on the basis of "not designed"? Can we make
any? Is there
any set of conditions that your "designer" could not achieve? In science, the important step is not "what can we predict if my hypothesis is true". It's "what tests could conceivably prove my hypothesis wrong, let's find those and do them".
You do realize that it has been centuries that people have recognized design in living forms. The problem was that all of that design observed was from the outside. It wasn't until technology was available to see the inner workings of an organism that we could observe design all the way down. Design in light of these new discoveries was not ad hoc, it was always predicted that life should appear designed if it were in fact designed. Thanks to new technologies it has been confirmed.
If there was no design apparent in living forms it would not confirm design. That is very obvious. There would be no evidence of design, no confirmation of design.
And of course, you have still completely and utterly failed to demonstrate that we actually observe design in any objective way. Unless you want to claim that we subjectively observe design, but that opens up an entirely new can of worms, doesn't it? Subjectivity screws basically any scientific idea, as whether or not the evidence exists in the first place is entirely up to the observer! No matter how many times I ask, you will not give me the model that lets us go from an object to whether or not that object was designed. All you ever do is appeal to "it looks designed". But that's not an objective measure of whether it was actually designed. That's your opinion. And if I disagree with you (as I have on numerous occasions), you have nothing to work with. You have no way forward. All you have is "well, you're wrong".
Design is demonstrated in life forms. That is the objective way to observe design. It is there whether or not you want to admit it, it is there and scientists observe it and admit that they do. They observe deliberate design for a purpose, they then claim that this observation of deliberate design is produced by evolutionary processes. That is not my opinion. This is MY OPINION...the design is not an illusion but is actual design. The evidence is the deliberate design observed in living organisms...the opinion of biologists and materialists is that it is produced by evolutionary processes...my opinion is that it is actual design and is not an illusion. Evidence = Design Opinion of materialists = produced by evolutionary processes
Opinion of theists and some non-religious biologists = actual design.
Let me show you the difference. Let's say that I think that the earth and all other planets go around the sun, and you think that the sun and all the other planets go around the earth. The evidence I provide of retrograde planetary motion is not subjective. It's not only there if you believe in it. It's present whether or not you want it to be! The conclusions reached as a result are not subjective either. It doesn't care how much you want to deny it, the evidence remains real whether you want it to or not. While if I want to deny your "evidence of design", all I have to do is say, "I don't think that looks designed", and I'm done. Because you have not shown anything objective.
The appearance of design is there whether or not you wish it to be. All biologists admit to observing the design in living forms. It is real, it is there and Biologists know this and have to have an explanation for it. If it were not there it would not be observed, it would not need an explanation and it could not mimic deliberate design if it did not appear as deliberate design. This refutes your "opinion" that it is a subjective appearance. No biologist I am aware of says that we are observing natural selection or evolution when they say they observe design.
Superficially, and with many of the analogies stretched to the breaking point. "The power plant of the cell!" Except that power plants really look nothing like that and do not work anything like that. "The eye is like a pinhole camera!" Except in every single aspect of its construction including the core functionality of how the image is received. "It's a motor!" Except that it looks and performs like no motor we have ever constructed.
You are in some serious denial.
One thing we agree on is that we who design magnificent machines and technologies can't touch the efficiency and precision of molecular machines. They appear engineered by an intelligence much much more intelligent than we are.
Can you defend your hypothesis without shifting the burden of proof? Your evidence of design is not valid. Please provide valid evidence. Never mind that there is strong and convincing evidence (genetic homologies, phylogenetic reconstructions, living and fossil intermediaries, et cetera) that many of these "designed" systems actually were evolved, and never mind that we can use evolutionary algorithms to "design" things that could easily fool people like you. None of that detracts from the fact that all that is going on here is a massive smokescreen to shift the burden of proof. Please demonstrate that your "evidence" is objectively valid.
You are the one being fooled. You see something intelligently designed "algorithms" and claim they are equivalent to actual natural processes that are suppose to be unguided and undirected.
The burden rests on those who claim the evidence of design is inaccurate or false due to illusion.
How many of these believe that this is actually design?
There are equally trained and educated biologists that believe it is actually design.
