ErosA433 did a great job explaining that evolution doesn't occur in huge jumps like a complex organ suddenly appears, it's lots of little baby steps, which he explains for the eye but you're still asking almost the same questions implying big jumps, even after his explanation about lots of small steps. So it almost seems like you don't understand his answer about the eye at all.

was saying how many died while trying to evolve a heart and circulation system
if they required it to live in the first place?
were they just born one day with a fully functioning heart?
if they were already alive, why need a heart?
how could you evolve a heart if you required one to live
does this clarify what i am trying to ask?
So 600 million years ago or so, jellyfish didn't need a circulatory system, so they didn't need a heart to live, but they did have a system called the entocodon. What the paper above is suggesting is that it appears there's a genetic link between the Jellyfish's entocodon, and the appearance of a mesoderm leading to a heart. So the heart didn't just suddenly appear, it would probably be something like gradual changes to the entocodon, leading to the mesoderm and heart.
One major difference that is apparent in the bilaterian and absent in the cnidarians is the presence of a third germ layer called mesoderm, of which the heart and circulatory system is one of its greatest achievements (Gilbert, 2000). Yet, as a jellyfish enters its reproductive stage, nerve cells, sensory cells, as well as specialised non-myoepithelial cells including striated cells can be found in a layer (Bishopric, 2005) called entocodon that separates away from the ectoderm. Entocodon of the cnidarians is comparable to the mesodermal germ layer found in bilaterian animals. Specific genes have been isolated in the jellyfish species Podocoryne carnea including Brachyury, Mef2, and Snail which have been shown to play a role in myogenesis (Spring et al. 2002), leading to the conclusion that these different genes may be the primordial beginnings of the heart and circulatory system that we see in later bilaterian species.

Presumably they just bow out because it is meaningless to discuss with someone engaging in bad faith argument to achieve the end of “GOD DID IT”

Because an animal doesn't try to evolve, it evolves due to genetic mutation that requires many generations. The animals (most likely jelly fish as pointed out by Arbitrageur, lived out their lives, produced offspring many times. They didnt DIE trying.
It is equally futile to argue with the people who say "evolution did it", despite no examples of populations of organisms ever evolving into something new. You would expect by now E. Coli (a prokaryote) to have become any other kind of prokaryote in a laboratory setting, especially after 75,000 generations, but E. Coli remains E. Coli.
Your faith in unintelligent design is no different than our faith in intelligent design. One refuses the possibility of the involvement of intelligence in the origin of intelligent beings, whereas the other fully accepts that intelligence begets intelligence.

Except we totally have seen it in action... anti-biotic resistance is a perfect example of evolution.

You have had why this particular line of reasoning is incorrect explained many times in numerous threads. I lack both the desire & the ability to repeat others who were more capable & knowledgeable than myself.
Plus there is no "faith in unintelligent design". Nor is there "unintelligent design" (excluding the designers of modern corporate logos. Minimalism is a curse upon mankind) You just made that up.

Specious... is exactly your whole involvement in this thread, none of your arguments are actually correct...
so explain the recurrent laryngeal nerve, seen across species, seen to be utterly stupid in length and direction... explain that one in 'gods infinite wisdom' who can apparently create nanomachines to do act as a hydrogen fuel cell, but apparently can't in that same wisdom... crate a nerve to take the shortest path...
amazing how it comes full circle.

Even the Laws you like to see as proof of Design are in reality constantly in Evolution.

please sit down for this, because:
you are ca. 37.2 trillion 'smaller organisms', we call them cells and they 'grew' mostly by starting cooperations to form bigger & more complex entities such as you.

which is why the theory of evolution so elegant: it didn't pop into existence as super complex entity, it evolved over time. Building and growing as you acknowledged earlier is how things work.

Did I say 'time did it'? I don't think so.
I am pretty sure I said cells are doing it.

horizontal gene transfer for one. Colony formation is also something we can observe. some microorganisms can incorporate others like algae f.e. changing how they function and aquire food. specialisation in colonies...
it's all there if you ask me, for details please contact the microbiologist you trust.
