Lol I am so tired of people saying it has not been observed, this is total [bless and do not curse][bless and do not curse] concocted by the people who absolutely refuse to do any research. Which makes me wonder why you would think you're entitled to any sort of cogent opinion when you refuse to look into it. It's so dumb like "yeah I have no knowledge in this area but here's what I know for a fact!" Lol, wow.
Anyway, it totally has been observed dude. Micro organisms and small insects, for example, have very short lives and so therefore we can observe many generations of, say, an E. Coli bacterium, in a relatively short amount of time.
Scientists will do a test like expose a sample of E. Coli bacteria to a certain antibiotic. 99% of the E. Coli die but the ones that survived happen to have an unusually thick cytoplast that helped them resist the antibiotic. These surviving E. Coli go on to replicate and they pass on that thicker cytoplast gene down to it's "children" and it's "children" to their "children." That's evolution.
It's really, really simple, it's a pattern in natural that is intuitive and very easy to understand. The faster cheetah gets to eat, it survives to pass on it's DNA, it's cubs inherit this DNA and themselves are more likely to be unusually fast.
There's not much to believe or not believe, we observe this in nature ALL THE TIME. The Heiki Crab in Japan used to have patterns on its shell that sometimes looked kind of like a samurai face. Fisherman would throw back in the water the crabs whos shells strongly resembled the face and kept and cooked the ones whos shell pattern was a little more abstract. Over the centuries it has reached the point where 99% of Heiki Crabs have the samurai face on its shell. This is because the ones with the face pattern were spared by humans and so they were able to continue to survive and pass on their DNA. Modern day Heiki Crabs are mostly descendants of these survivors and therefore look like them, complete with the samurai face on their shells. This is an example of artificial selection because man was the driving force behind the species' change instead of a natural force, or, natural selection. Dog breeds are an example of artificial selection. The greener lizard is less likely to be noticed and snatched up by the snake. So it is more likely the greener lizard will survive to pass on its genes, and its greener lizards from there on. Thats natural selection.
So yeah, its very much observable. The Theory of Evolution simply states and describes this pattern of biological change in natural. By the way, thats the difference between a law and a theory. A law basically states something. The law of gravity. A theory states, describes and explains something. This is evolution, this is how it works, this is why this works. If there were a hierarchy of scientific classifications then a theory would be higher than a law.
And as far as this whole "the jury is still out, the scientists dont agree" um, no. Sorry. The question of things like how did the biogenesis events go down, were there any more subspecies of australopithecus we havent found, did they cross the arabian peninsula, how can the synthesisation of RNA naturally occur? These are the question scientists are asking and they are often not agreeing with each others answers. They are not still wondering if evolution itself is real. I mean dude, come on these are scientists, they study this for a living, if evolution was false then all of modern biology would be false and so many things that have come from that understanding, genetics, cloning, medicine, oncology etc. wouldnt be around. It's proven to work because everything we've built off of it works. Also because it's such a simple concept that makes complete sense to anyone not dumb enough to think God will destroy them if they believe in it. Sucks to live through fear huh. I was always taught God loves us. So why should I fear the truth? Honestly I don't think God has a problem with evolution.
Problem 1: No Viable Mechanism to Generate a Primordial Soup
According to conventional thinking among origin of life theorists, life arose via unguided chemical reactions on the early Earth some 3 to 4 billion years ago. Most theorists believe that there were many steps involved in the origin of life, but the very first step would have involved the production of a primordial soup -- a water-based sea of simple organic molecules -- out of which life arose. While the existence of this "soup" has been accepted as unquestioned fact for decades, this first step in most origin-of-life theories faces numerous scientific difficulties.
In 1953, a graduate student at the University of Chicago named Stanley Miller, along with his faculty advisor Harold Urey, performed experiments hoping to produce the building blocks of life under natural conditions on the early Earth.
4These "Miller-Urey experiments" intended to simulate lightning striking the gasses in the early Earth's atmosphere. After running the experiments and letting the chemical products sit for a period of time, Miller discovered that amino acids -- the building blocks of proteins -- had been produced.
For decades, these experiments have been hailed as a demonstration that the "building blocks" of life could have arisen under natural, realistic Earthlike conditions,
5corroborating the primordial soup hypothesis. However, it has also been known for decades that the Earth's early atmosphere was fundamentally different from the gasses used by Miller and Urey.
The atmosphere used in the Miller-Urey experiments was primarily composed of reducing gasses like methane, ammonia, and high levels of hydrogen. Geochemists now believe that the atmosphere of the early Earth did not contain appreciable amounts of these components. (Reducing gasses are those which tend to donate electrons during chemical reactions.) UC Santa Cruz origin-of-life theorist David Deamer explains this in the journal
Microbiology & Molecular Biology Reviews:
This optimistic picture began to change in the late 1970s, when it became increasingly clear that the early atmosphere was probably volcanic in origin and composition, composed largely of carbon dioxide and nitrogen rather than the mixture of reducing gases assumed by the Miller-Urey model. Carbon dioxide does not support the rich array of synthetic pathways leading to possible monomers…

Likewise, an article in the journal
Sciencestated: "Miller and Urey relied on a 'reducing' atmosphere, a condition in which molecules are fat with hydrogen atoms. As Miller showed later, he could not make organics in an 'oxidizing' atmosphere."
7The article put it bluntly: "the early atmosphere looked nothing like the Miller-Urey situation."
8Consistent with this, geological studies have not uncovered evidence that a primordial soup once existed.

There are good reasons to understand why the Earth's early atmosphere did not contain high concentrations of methane, ammonia, or other reducing gasses. The earth's early atmosphere is thought to have been produced by outgassing from volcanoes, and the composition of those volcanic gasses is related to the chemical properties of the Earth's inner mantle. Geochemical studies have found that the chemical properties of the Earth's mantle would have been the same in the past as they are today.
10But today, volcanic gasses do not contain methane or ammonia, and are not reducing.
A paper in
Earth and Planetary Science Lettersfound that the chemical properties of the Earth's interior have been essentially constant over Earth's history, leading to the conclusion that "Life may have found its origins in other environments or by other mechanisms."
11So drastic is the evidence against pre-biotic synthesis of life's building blocks that in 1990 the Space Studies Board of the National Research Council recommended that origin of life investigators undertake a "reexamination of biological monomer synthesis under primitive Earthlike environments, as revealed in current models of the early Earth."
12
Because of these difficulties, some leading theorists have abandoned the Miller-Urey experiment and the "primordial soup" theory it is claimed to support. In 2010, University College London biochemist Nick Lane stated the primordial soup theory "doesn't hold water" and is "past its expiration date."
13Instead, he proposes that life arose in undersea hydrothermal vents. But both the hydrothermal vent and primordial soup hypotheses face another major problem.
The Origin of life hasn't been observed and other things and there are other problems eg
Humans Display Many Behavioral and Cognitive Abilities that Offer No Apparent Survival Advantage But actually I agree with you that science explains the specifics of how God done things and the bible deals with spiritual truths. God is the greatest biologist. I still think there are still a lot of unexplained things in biology and it's still not a completed science.
