    "144 tanks cross"
    "346 tanks cross"

So not only would you need to know that there is a spy and that the spy counted tanks (instead of, say, planes or flowerpots), you would also need to know the exact number he counted and that the spy has not counted wrong. You'd also need to know how he phrased the answer.

    So, so wrong. A lot of creationists would be happy having a critique of evolution (like a look at the lack of intermediate species in the fossil record, among other things). But mentioning the suspicious parts of evolution is somehow labeled establishing religion.

    Please open any copy of Darwin's "The Origin of Species", please. It is, after all, the book that brought the issue up to public scrutiny in a big deal. And -- contrary to some opinions -- just reading something does not mean that you automatically have to agree with it.

    For brevity's sake, I'm just giving you a few of the chapter headings in it:

    * Difficulties on the theory of descent with modifications
    * Absence or rarity of transitional varieties
    * Organs of small importance
    * On the imperfection of the geological record
    * How far the theory of natural selection may be extended

    And these are just some of the headings. The text itself contains an even more thorough look at what the theory can explain; what it can't explain and what, if found to be an incorrect assumption, would immediately break its back. The entire thing is a defense of a theory against a torrent of very intelligently put criticisms and pointing out of difficulties.

    And, as far as I can remember, we raised or got shown many of the same questions during our school education on this topic. They were discussed and at the end, almost everyone was convinced of it. Not because the teacher said so, but just because it stood the test of an onslaught of people trying to poke holes in it ... and it still does!

    I know virtually no other scientific idea that was, is and probably will be for our entire lifetime, put under so much scrutiny. And for some reason, no counter-argument has yet managed to break it down; the best they got to, was to show us parts where we did not understand the full implications of the theory yet. And then, by examining it closer, we discovered elements of it that were even more amazing than we thought possible.

    Things like the existence of DNA; that horizontal gene transfer is possible between different individuals, groups or species; the role of retro-viruses; the quickness with which adaptation can act, given enough outside pressure; and so on.

    So no, I am afraid you overlook just how deeply this entire theory is constantly being evaluated and how hard it is getting poked at. Nowadays, people want to break it, just to see what amazing things we have not yet learned about it.

    So, we need to keep religion completely out of education standard.

    No, actually we don't. It depends on what the people want, since this is a democracy. If the people are a bunch of religious nuts, then the education standard needs to include religion (whichever flavor the majority wants) and omit evolution (of that's what a majority wants). This is the price of democracy: you have to share with all the other people you co-inhabit a region with.

    Be careful where you're heading with that idea, as what you propose is exactly what ages of very intelligent political philosophers have correctly pointed out to be the most brutal and merciless part of democracy: The tyranny of the majority.

    If you take a democracy to mean that you put everything to a vote and then blindly enforce what the majority demands, you quickly end up in a nightmarish hellhole.

    After all, what if a populist puts up to vote that you must buy and memorize a particular book and you are told that 51% of the people agreed to that?
    What if it is then put up for the vote, that due to the way voting works, all parties should be merged, and 51% of the people agree?
    What if is then asked, what you should do with a certain 1% of the population, and 51% of the people agree to seize their property?

    With just three, small votes, you're in a wonderful cross between Mao's China, Stalins Soviet Union and -- and this is up to you to choose -- Hitler's Germany, Mussolinis Italy, Franco's Spain, Europe during the Inquisition, the USA during the Indian Displacement, Cambodia under the Khmer Rouge, etc. pp.

    After all, remember that no-one said that those 51% of the population were always the same 51%. As an old adage goes: When they came for the Communists, I didn't say a word. When they came for the Gypsies, I didn't say a word. When they came for the Jews, I didn't say a word. When they came to get me, there was no-one left to say a word to save me.

    No, the power of democracy does not lie in the tyranny of the majority; it lies within the civil discourse between all; majorities, minorities, loud or silent. It lies within the concept that everyone must be included to agree on a best course of action. All safe-guards in a democratic society must be laid out to guarantee this fundamental concept. That it must be impossible for any part, to take away the voice of any other part.

    And, not to put too fine point on it: Taking away the voice of reason, the process of rational and impassioned evaluation of how we think the world works -- even if that reason might arrive at a conclusion you deem erroneous -- in favour of the voice of dogma, is to deny one of those safeguard of democracy.

    TL;DR:
    The difference is that those teaching evolution do not deny you your right to teach your kid your point-of-view; they only deny you the option of saying that your view is the only way to look at it. In contrast, most creationists/intelligent designers want to force a single point-of-view, to the exclusion of all the others; especially if they come from an impassioned look at the world as it is.

    I understood that. What I was more getting at was your statement that the view of the stars should be pretty good -- as good as a near-vacuum.

    But actually, during most Martian weather patterns, the view to the stars is pretty shoddy. After all, it's not the air molecules that are blocking your view to the starts on Earth (at night, at least); the three worst culprits are moisture (in the form of clouds/mist), solid airborne particles (dust, sand, ash, etc.) and the simple fact that the overall density of the atmosphere fluctuates from heat convection -- the latter leading to "twinkling" stars.

    Now, Mars has virtually no airborne moisture and only high-altitude ice clouds, which is a boon. Unfortunately, this also means that it contains much more solid particles which stay afloat much longer; as they're not washed out of the atmosphere via fog, rain, snow or hail. The third is heat convection. While it helps that there's less air that moves around (which is why modern telescopes are built as high up as possible on Earth), Mars has a much stronger temperature tide. In other words: The difference in atmospheric density between hot and cold areas.

    On Earth, this seldom amounts to more than a fraction of a percent compared to the overall density.
    Whereas on Mars, the density can quite easily vary by 10% even if it's just modestly heated up.

    So, on the balance of things, yes, Mars has a better astronomical weather than Earth, but not by much. And in contrast to the moon, where you can see the stars even during the day, on Mars you only see a reddish haze.

    Again, as a comparison: moving just 100 times slower than light is still pretty damn fast. Having 100 times less atmosphere than Earth is, for many purposes, still pretty damn dense.

Of course then we'd have to engineer humans that didn't suffer bone decalcification due to the low gravity...

    Snarky as your comment may have been meant, I think you need to check your numbers again what constitutes "so thin it's basically vacuum."

    Mars has an average surface atmospheric pressure of 0.636 kPa. Earth has 101.325 kPa. So yes, while it is 160-times thinner, that's still pretty thick, especially if dust is kicked up. After all, remember that with 1/3rd gravity, much less air friction and no moisture, dust particles can stay afloat for quite some time.

    And then, compare that to the moon, with a pressure of 10^-7 kPa (~1 nPa), Mars still has a 6.36 million times denser atmosphere. And compared to interplanetary space, that's still practically solid, as space has 400.000 times less pressure.

    In other words: If Mars is a near-vacuum at nearly 10^17 times more molecules per cm than interplanetary space, then a snail that moves at only 3*10^10 cm/s.
