Scientific theories are never "proven true." They are merely accepted as the best explanation currently available, based on the evidence collected to date. They are subject to being falsified by new evidence by any time.
So the theory of evolution has not been "proven true" but it is the best explanation of the evidence we have.
Wrong, theories get proven all the time by facts. There is no evidence that we evolved from lower life forms, it is just asinine and laughable to suggest there is.
So how do you account for observed instances of speciation--both in the lab and in the field?
I understand there were instance in the 50's where they stated there was these observed instances, but its just not a fact in reality, not when placed under an observational microscope so to speak.
Why the Miller–Urey research argues against abiogenesis

In this day and age, it is imperative that we all learn to think for ourselves. Don’t let me tell you what to think, and don’t let anyone else tell you what to think either. Do your own research and come to your own conclusions. The following are 11 reasons why evolution is just a fairy tale for adults…
#1 If the theory of evolution was true, we should have discovered millions upon millions of transitional fossils that show the development of one species into another species. Instead, we have zero.
#2 When Charles Darwin came up with his theory, he admitted that no transitional forms had been found at that time, but he believed that huge numbers certainly existed and
would eventually be discovered…
“Lastly, looking not to any one time, but to all time, if my theory be true, numberless intermediate varieties, linking closely together all the species of the same group, must assuredly have existed. But, as by this theory, innumerable transitional forms must have existed,
why do we not find them embedded in countless numbers in the crust of the earth?”
#3 Even some of the most famous evolutionists in the world acknowledge the complete absence of transitional fossils in the fossil record. For example, Dr. Colin Patterson, former senior paleontologist of the British Museum of Natural History and author of “Evolution”
once wrote the following…
“I fully agree with your comments about the lack of direct illustration of evolutionary transitions in my book. If I knew of any, fossil or living, I would certainly have included them …. I will lay it on the line –
there is not one such fossil for which one could make a watertight argument.”
#4 Stephen Jay Gould, Professor of Geology and Paleontology at Harvard University, once wrote
the followingabout the lack of transitional forms…
“The absence of fossil evidence for intermediary stages between major transitions in organic design, indeed our inability,
even in our imagination, to construct functional intermediates in many cases, has been a persistent and nagging problem for gradualistic accounts of evolution.”
#5 Evolutionist Stephen M. Stanley of Johns Hopkins University
has also commented on the stunning lack of transitional forms in the fossil record…
“In fact, the fossil record does not convincingly document
a single transition from one species to another.”
#6 If “evolution” was happening right now, there would be millions of creatures out there with partially developed features and organs. But instead there are none.
#7 If the theory of evolution was true, we should not see a sudden explosion of fully formed complex life in the fossil record. Instead, that is precisely what we find.
#8 Paleontologist Mark Czarnecki, an evolutionist,
once commented on the fact that complex life appears very suddenly in the fossil record…
“A major problem in proving the theory has been the fossil record; the imprints of vanished species preserved in the Earth’s geological formations. This record has never revealed traces of Darwin’s hypothetical intermediate variants –
instead species appear and disappear abruptly, and this anomaly has fueled the creationist argument that each species was created by God.”
#9 The sudden appearance of complex life in the fossil record is so undeniable that
even Richard Dawkins has been forced to admit it…
“It is as though they [fossils] were just planted there,
without any evolutionary history. Needless to say this appearance of sudden planting has delighted creationists. Both schools of thought (Punctuationists and Gradualists) despise so-called scientific creationists equally, and both agree that the major gaps are real, that they are true imperfections in the fossil record. The only alternative explanation of the sudden appearance of so many complex animal types in the Cambrian era is divine creation and both reject this alternative.”
#10 Nobody has ever observed macroevolution take place in the laboratory or in nature. In other words, nobody has ever observed one kind of creature turn into another kind of creature. The entire theory of evolution is based on blind faith.
#11 Evolutionist Jeffrey Schwartz, a professor of anthropology at the University of Pittsburgh, openly admits that “
the formation of a new species, by any mechanism, has never been observed.”
