I don't know about lying, but what many
scientists (not to be confused with science itself) do is judge/conclude/condemn entire subjects and theories without any proof except their own opposing theories. This, to me, shows extreme
bias and emotionalism that pure science is not supposed to have. Sadly, most human beings are incapable of pure scientific work. They always want to draw conclusions on a given subject and then use those conclusions to bash any other ideas out there with words like bogus, poppycock, fiction, fancy, etc. etc.
A simple example is the Ancient Astronaut theory. Other than the proponents, it gets ridiculed left and right in the mainstream since this might contradict Darwin's theory of pure evolution on earth despite the time frames needed to create DNA being more likely to get a fully assembled working 747 by nature than DNA in the same time frame. No, ignore all evidence that pokes holes in existing theories and instead look for holes to poke in alternative theories and simply say that the holes they poked aren't a big deal and easily ignored. THAT is what scientists do. They're not supposed to give opinions, only present facts and statistical likelihoods as they analyze them to be now. Conjecture is one thing, but ridicule is another. The history books paint religion as ignorant poppycock yet you see the same sorts of thing from scientific groups all the time. Pointing out flaws is fine. Being vindictive, totally dismissive and essentially excommunicated is another. You see labels like "fringe scientists" (i.e. ones who research and/or believe in another non-mainstream theory) and pseudo-scientific theories, etc. Yet for all its claims, Darwinism is just an observation of similar species and now with similar genetic markers (with no far-out other worldly genetic structure to compare against; for all we know life everywhere might look similar if that's the only way it can work).
That's just one example, but don't believe for a minute that scientists are these non-judgmental almost Star Trek "Vulcan-like" people that just say fascinating when they find something new. They're set in their ways and methods and beliefs the same as anyone else. They simply believe something different based on observational records rather than myth, etc.
Religion clashes with Science because their myths are whole-sale off in terms of time periods, etc. The fact you see the churches now crawling away from some of that is simply an unspoken admission that this planet has been here way longer than the time periods implied. But myth and hand-me-down history makes more sense in terms of error than anything else. They wrote what they saw and believed and potentially misunderstood. That doesn't mean they just made crap up either. Yet much of science relies too much on things like Carbon Dating which has potential flaws if the "constant" it relies on is actually variable.
You have hard dates for things like the Sphinx and this nice and neat history book explanation of our past like its simple points of fact. You later find water weathering erosion that pushes the time period back to nearly double the supposed date and it doesn't fit the puzzle anymore and is in danger of making the entire puzzle fall apart. So rather than look for the new puzzle, scientists just deny the evidence of water erosion that points to it being thousands of years older. That's not how "science" is supposed to work. That's how hard-headed people who don't want their life's work obliterated as total error behave. You see the same in archeology in general and some places like Egypt won't even let the alternatives do research there for fear they MIGHT find something that unravels part or all of their own life's work. Sadly, scientists are all too human and all too full of it in the grand scheme of things.
Did they really find a Higgs-Boson ("we think so") or are they trying to justify $10 BILLION in wasted money to look for something that's not really there? Dark matter? It's a non-proven to exist band-aid for a massive flaw somewhere in Physics. We don't understand gravity AT ALL (just its effects) and it's screwing up the entire model of the Universe. Of course if we did understand it and knew how simple it was to get around the Universe once the true nature was understood, we'd slap ourselves in the head. But having two areas of Physics that simply do NOT work together (you get
infinity when you try to combine them, proving something is WRONG WRONG WRONG in at least one of them), we can't just throw the last century out and look for the truth. We keep looking for band-aids to make the ridiculously overly complex math in Quantum Physics to work when it obviously doesn't (i.e. something is wrong in the proposed models; yes parts explain certain behaviors great, but overall on a grand scale it just falls apart and no surprise given the math describes the behaviors rather than source of it).
Yet its those same physics that say no other life could have possibly visited or found earth. We're too remote. We're too far away. It's just not possible to cover those distances. And we make these conclusions based on our own current knowledge and technology (giant firecrackers to get into space). It's a total HOOT to see grown men make absolute statements based on their own ignorant rather than just admit WE aren't there yet but that doesn't mean that's all there is. We think we can understand all of Physics in a couple of hundred years. The arrogance is high. The knowledge is small.
So you won't see me trashing theories. Is Ancient Aliens bunk? Possibly. Are we descended from hominids common to the Apes? Possibly. Did a Creator being MAKE us from the "earth"? Possibly. Is it possible to combine all three into one and still have something that works? Yes, it seems it is. But that's a "fringe" idea and there's only interpreted circumstantial evidence and myths about "gods", etc. But coming out of "nothing" is just as bizarre to me. You've got alternatives now to the Big Bang Theory and they get poo-pooed also. You've got String Theory and you've got Loop Quantum Gravity and just watch some of their proponents bash the other one (in a calm way of course...usually, although one only need to look at people like Lubos Motl to see insults in action).
It's a good thing there's lots of salt on this planet because you have to ingest it constantly when you read something.
