They assume things all the time, could have/may have, because they either have no idea what happened, or they do not want to share with the public what even they know. Evolutionists are confidently throwing around such non-factual concepts as abiogenesis, something supposedly describing the spontaneous birth of life forms from chemicals and other amorphous material, pretty much another definition for miracle, and speciation, which is gradual evolution spelled differently. In reality, as basically even the authors of this study admit no one actually knows how life has appeared on our planet, a reminder of the fact that Darwin's On the Origin of the Species does not address the question of the origin of species and that the title of his book is a false label placed on an empty box.
To have a life form, any life form, you would first have to have its DNA, and the origin of the DNA is a capital problem for the theory of evolution, another something no one wants to talk about. Someone did talk about the origin of the DNA, though, and that was no other than Francis Crick, its co-discoverer and a Nobel Prize recipient for that very reason. According to him, and he stated this in his published book, the DNA was produced outside planet Earth by an advanced civilization. Considering that the DNA contains coded information, this is something Lady Evolution and Aunt Natural Selection, two imaginary characters in a fictional story presented as fact in schools and universities, precisely how the six-day fictional creation story in the Bible is described to trusting churchgoers would be incapable of putting together. On the other hand, according to both genetics and field theory, Crick's assertion makes perfect sense.
When we also consider its amazing information storying capacity, that the DNA acts during the process of reproduction in conjunction with its printout, something called RNA, and the fact that someone has placed within our general biological system genetic devices that make sure the copying of the genetic information during the reproduction process is done correctly so that no mistakes, no "evolutionary" mutations happen, it is hard to believe scientists have not yet figured out that the DNA could not be a chance product of adaptation to changes in the environment, a claim that comes in conflict with the very standards imposed by the scientific method of research. It is either that, or they do not want to admit to the reality this Nobel Prize recipient describes in his book.
Most everyone in the scientific community would agree, off the record of course, the claim that gradual biological evolution could occur spontaneously in nature and that on top of everything else it occurred over millions of years does not just defy common sense. It is biologically and genetically impossible, and, once again, one does not need to be a biologist or a geneticist to be able to understand that. Common sense does the trick just fine.
Random natural events do not code genetic information, nor could an assumed process of adaptation cause changes in an existing genetic code during the life of the species. As most of us know, this is something only a genetic engineer could do. Then there is the indisputable fact that, to be able to exist and reproduce as a species, you would have to have all you organs together and in working condition from day one of you setting foot on this planet. If you don't, you are the last generation of your species, whatever form or shape you are in as a species since, according to evolutionists, once again, your organs and functions would be in a transitional stage for millions of years.
As publicly admitted even by some of those on-again, off-again supporters of Darwinism, with American evolutionist Stephen Jay Gould being one of them, there has been a code of silence imposed on scientists on this subject, something similar to the UFO phenomenon and the contacts we made for thousands of years with extraterrestrials being a taboo topic for the media. Albert Einstein, for example, would often weigh in on all sorts of topics of great human interest. He has never discussed though evolution publicly, one way or the other, and yet we know for a fact he was well-aware of the controversy.
The standard explanation, as acknowledged by Gould, is one does not want to tell it the way it is for that gives comfort to church creationists. For a rational human, church creationists have done actually a pretty good job at destroying the appearance of legitimacy of the institution of religion and of its dogma from the moment it was established, no redeeming chance there either. In other words, the current rule of the game is, you either support in public an otherwise undefendable theory of evolution, as described by molecular biologist Michael Denton in Evolution: A Theory in Crisis, or you keep quiet about the huge problems with the theory. The alternative to that is you risk being ridiculed, your books are not going to be published, and you may even end up loosing your teaching job. As it turns out, though, not everyone abided by this rule.
The code of silence imposed by or rather reinforced through the academia resulted in the fact that only scientists that happen to have a very intimate association with what some would call religion, belief in some kind of deity that is not always one and the same with the god of religion are being heard speaking against evolution, and even though some of them are Nobel Prize recipients in all sorts of science related fields, the evolution propaganda machine calls them creationists and invites the public to dismiss on account of that their otherwise valid scientific argument against gradualism.
The other problem with the fact that evolution propagandists are claiming only creationists state evolution is no fact, many churches, with the Catholic Church and the Church of England being on top of the list are officially endorsing these days evolution. As you are going to see in A Time of Change, they do not do that because they sincerely believe evolution is fact, almost nobody believes that and we have the Gallup polls to prove it. And while we have Catholic Church officials on record declaring evolution the best available explanation for the existence of the universe (obviously false) and everything in it (obviously false, biological evolution has nothing to do with the origin of the universe and everything in it), this endorsement comes with a caveat. The no so subtle implication is, as long as their god was in charge of the process, evolution happened the way Darwin, a god believer, said it happened.
The actual reason why they would rather endorse evolution then have intelligent design discussed in science class is that they want to protect a status quo their multi-billion-dollar preaching industry that also happens to be a reliable instrument of mass mind-control depends on. For, and this may cause a shock to most churchgoers, the other actual reason why church creationists endorse these days evolution is the same reason why a few years ago they surreptitiously abandoned their support for intelligent design.
Indeed, creationists and evolutionists were equally happy when at the end of the 2005 trial in Dover, Pennsylvania, a judge of no scientific expertise officially banned discussing intelligent design in public schools under the false pretense that ID was religion. Not according to Socrates, who was sentenced to die because he was critical of religion and of religious authority and who made a non-religious strong case for design some 2,400 years ago, and not according to dozens of bona fide scientists along the entire known history of our civilization all the way to present days. He also declared evolution a sound theory, for a judge's court is where you go when you want to establish if a scientific theory is fact or fallacy. Everyone needed though the ban because, in reality, ID stands exactly for what Francis Crick said in Life Itself about the origin of the DNA, and that too has nothing to do with religion: The DNA is not from Earth. It was created by an advanced civilization.
Significant positive change in the way we exist on this planet is much needed, and it could only be the result of a significant improvement in the way we understand our origin, the nature of reality, and the purpose of life. Meanwhile, the protectors of the status quo continue to allow every new generation to be indoctrinated with religious irrational, at the same time issuing science papers on practically inconsequential "new studies" revealing decades-old "new theories." The studies are conducted by scientists with credentials and their inconsequential results are published in impressively named science journals to give them the aura of credibility they are after. This is how someone out there keeps the public's attention away from what is really at stake here.
