For the Theory of Evolution to be credible, life had to have evolved from single celled organisms with very simple systems, to multi celled organisms with very complex, interdependent systems (i.e., the cells in the lung need the red blood cells from the circulatory system to do their work, the muscles which power respiratory and peristalsic intestinal action require both the circulature and a nervous system to guide their work, etc.,... as in "interdependent").
In as much as these complex systems are inescapably dependent upon one another, they must all have developed at rougly the same time to have survived the "survival of the fittest" cut. When was that? Where is the fossil record of that?
The fossil record, however, contains only the former (simple, single celled) and the latter (complex, multi system) with no fossil evidence of the billions of missing "developmental" stages.
If they existed, there would have had to have been billions of them, and we would surely have found some by now.
On the other hand, the existing fossil record does comport with the Biblical History of Creation. Oceans first, then creatures, with no "evolutionary" link between the two.
That you are trapped into depending on man's (and your own) intellect for explanations about such things makes it easier to understand why you are blind to the Truth. But your blindness does not make Truth a lie, nor will it ever make a lie the Truth.
I send my sincere condolences about all those "peer reviewed" papers you've wasted so much valuable time on. There nontheless remains hope for you for so long as you draw the Breath which God Breathed into you.
The best modern take on this development is that multi-cellulars came about as a conglomeration of co-operative multi-cellulars. And, in fact, "fossils" of this circumstance are abundant in, for example, the similarities between the DNA's of certain still-freedwelling prokariotes and their productive counterparts in multi-cellular creatures, such as our mitocondria and plant cell's chlorophyl.
Amongst the reasons you can't find much mineral imprint fossil evidence before multi-cellulars is that there were no mountains rising above the ocean floor, and hence no significant leaching of calcium into the ocean. No calcium, no bones, Sherlock.
Several living animals with guts have only the most primitive neural nets - for example, hydra, jellyfish. All they need is to be able to intake and expel water. Sponges have no neural net at all, and their central cavity isn't really a gut. How hard is it to imagine that sponges developed a neural net to facilitate their filter feeding, that they began to also accumulate material in their gut and derive nutrition from it, and the gut evolved over time under that selective pressure?

Why thank you. And may the Good Lord in turn grant you the grace to realize when you're about to be a patronizing and sanctimonious twit, and to resist that temptation.
