Leonardo, it seems as though you are trying to corner me into saying that I don't know about evolution so that you can suggest that this is why I am skeptical. I also think this is because you are ticked off at me saying the same thing to you in another thread and this is your little vendetta. Because if you weren't thinking this you would clearly SEE where I have pointed out what it is I have a problem with. It gets tedious to repeat over and over again so I will suggest that you go back and read my previous posts because its clearly outlined.
I have a problem with science saying that its SCIENCE through and through but not pointing out where it is NOT SCIENCE when the presented opinion is one in which they are in agreement with. I have a problem with them not following their own rules. The presentation of the science theory to the public as a fact when it is just a scientific theory is what bugs me. And I DO know the difference between a theory and a scientific theory I understand that its not the same as a guess.
Here's an example of a suggested school curriculum. This documents what the NSTA thinks should be taught to 8th graders in science class.

Q: In general, how should I address questions from students and parents about alternative theories of biological evolution?
A: It is important to first acknowledge that different viewpoints and ideas exist regarding the history and nature of life on Earth. In the discussion that may ensue, you should define the word theory as it is used in the scientific community. In particular, you should note that a theory is a well-substantiated explanation that incorporates facts, laws, inferences, and tested hypotheses, and theories can be tested, modified, and rejected. Theories are valuable because of their explanatory power and their usefulness in making and testing predictions. The alternative "theories" that typically serve as the springboard for student and parental questions tend not to be scientific theories because they cannot be tested, they lack explanatory power, and they do not provide the basis for additional research. That is why these alternative "theories" are being omitted from the curriculum, not because of censorship or unfairness.

a. Radioactive dating and relative dating (
i.e. stratigraphy, fossils) are used to estimate the
time rocks were formed.
c. The earth’s atmosphere has changed over time. For example: The dramatic changes in
earth’s atmosphere (i.e. introduction of O2) which were affected by the emergence of life
on earth.
http://www.pbs.org/wgbh/nova/transcripts/3111_origins.htmlYes I know that NOVA is not a science program per se, however when a Science program routinely wins AAAS Science Journalism Awards it does show that they are being recognized as a sort of science authority.
If you read the transcripts from their program you will see these kinds of statements:
QUOTE
MIKE ZOLENSKY (NASA Johnson Space Center): If you look under your bed, you'll find that little bits of dust are collecting together into large dust balls. And something like that must be what happened in the solar system, too.
NEIL deGRASSE TYSON: What started as a giant ball of debris floating in space turned into Earth, but four and a half billion years ago, it wasn't exactly home sweet home.
MIKE ZOLENSKY: The Earth, at some point, was totally molten, a big droplet of melt just floating in space.
NEIL deGRASSE TYSON: How did it change from a raging inferno like this to a place we all know and love? It seemed a series of massive disasters was the best thing to hit the infant planet.
BILL HARTMANN (The Planetary Science Institute): We all hear about the impact 65 million years ago that wiped out the dinosaurs. And you're getting that kind of impact something like once a month on the early Earth.
NEIL deGRASSE TYSON: And more clues are embedded within these rocks, fragments left over from the first hours of Earth's life.
STEPHEN MOJZSIS (University of Colorado): Very little is left behind from the Earth's earliest time period, but what is left behind has revealed to us a planet much more complicated than we ever thought.
These men are scientists not paid actors. They are highly educated and well known scientists. I do imagine that if a person was watching them and knew their credentials they would be recognized as an authority in the field.

http://www.pa.msu.edu/acoustics/wmh.htmAgain these men are scientists, so the big come back that members of the science community don't support the rogue Discovery Channel or Nova groups going out blabbing all sorts of crap that's not been proven, is absolutely a ridiculous argument.
My statement is correct. When scientists promote their leaps of faith (aka in my opinion as religion) as fact if the rest of the community agrees with the leap, they don't come forward to insist that they should be more cautious about jumping to conclusions.
But let a creationist start speaking out and all hell breaks loose. Most of the arguments are directed at creationists, not just general skeptics like myself.
Now to me, for all we really know, there could be totally different explanation that we don't have the knowledge to comprehend yet. For example the way in which it was believed that the earth was the center of the solar system. Until it was found that we have a heliocentric solar system all sorts of wrong conclusions were presented in science. (Which ironically the science community tries to pass off on religion)

QUOTE
It has been assumed that Nb and Ta are not fractionated during differentiation processes on terrestrial planets and that both elements are lithophile. High-precision measurements of Nb/Ta and Zr/Hf reveal that Nb is moderately siderophile at high pressures. Nb/Ta values in the bulk silicate Earth (14.0 ± 0.3) and the Moon (17.0 ± 0.8) are below the chondritic ratio of 19.9 ± 0.6, in contrast to Mars and asteroids. The lunar Nb/Ta constrains the mass fraction of impactor material in the Moon to less than 65%. Moreover, the Moon-forming impact can be linked in time with the final core-mantle equilibration on Earth 4.533 billion years ago.

DNA evidence suggests that the first eukaryotes (green plants) evolved from prokaryotes (through endosymbiotic events) between 2500 and 1000 million years ago. Fossils of eukaryotes that resemble living brown algae have been found in sedimentary rocks from China that are 1700 million years old, while possibly the oldest photosynthetic eukaryote, Grypania, comes from rocks 2100 million years old. Note that the diversity of modern algal groups, and particularly of their chloroplasts, suggests that these endosymbiotic events were not unusual. Modern algae comprise a range of organisms with very different structures but identical photosynthetic pigments. This suggests that very different host organisms have formed a symbiosis with the same photosynthetic cells. That is, the algal groups must have evolved through separate endosymbiotic events, and the group as a whole is identified on the basis of a similar level of structure, rather than on its evolutionary origins. Such groups, where the members have several different evolutionary origins, are described as polyphyletic.
In all of the articles I have posted you see the words, assume, might, suggest, etc. So why the big flip out on people who say I'm going to hold back on accepting this theory. I'm only going to view it as a theory?
This article says the same thing that I have been saying
http://www.talkorigins.org/faqs/evolution-fact.htmlQUOTE
. Biologists consider the existence of biological evolution to be a fact. It can be demonstrated today and the historical evidence for its occurrence in the past is overwhelming. However, biologists readily admit that they are less certain of the exact mechanism of evolution; there are several theories of the mechanism of evolution.
Now read a little bit further and you will see what I mean about the Creationist agenda being the issue they wish to address. Its as I said, evidence that they will pipe up loudly against any perceived criticism of the theory but only when its to batter down Creationists. I don't agree with creationists but I do have criticisms of the theory.
Let me state again, I accept EVOLUTION where it is a real scientific theory, that is in the evidence. But in the mechanism I am skeptical that they have figured this out yet. When I state this I'm most often accused of not knowing the difference between scientific theory and regular theory, then I'm accused of falling for the Creationist agenda or getting my information off the Creationists website etc etc etc. Or I'm accused of rejecting evolution outright. I have never stated this.
The article further goes on to state this

In science "fact" can only mean "confirmed to such a degree that it would be perverse to withhold provisional consent."
Ok so how is it then, that when I say I don't think that scientists can really say that they know what the surface of the earth looked like 4.4 billion years ago I'm an uneducated fool?
No its just reasonable doubt. Its reasonable to see that its impossible for them to make any conclusive statements about the earth that long ago. All their data is based on our capability to comprehend evidence we have at our disposal now, and theory we have developed with our limited understanding.
I do not believe that modern science has worked out the kinks just yet and just like X is that variable of a more complicated equation I believe that the answers to the origins of life on this planet are going to be more complicated and more simple than we could possible imagine right now.
And it is on this FACT that I base my skepticism.
