In choosing topics for this blog, I try not to have it simply devolve into taking random pot shots at crazies. Loony ideas are a dime a dozen, and given the widespread access to computers that is now available, just about anyone who wants one can have a website. Given these two facts, it's inevitable that wacky webpages have sprouted up like wildflowers on the fields of the internet.
When an alert student brought this one to my attention, however, I just couldn't help myself. Entitled "Did Humans Come From Another Planet?", it represents one of the best examples I've ever seen of adding up a bunch of facts and obtaining the wrong answer. The only ones who, in my experience, do this even better are the people who write for the Institute for Creation Research, and to be fair, they've had a lot longer to practice being completely batshit crazy, so it's only to be expected.
Anyhow, the contention of the "Did Humans Come From Another Planet?" people can be summed up by, "Yes. Duh." We are clearly aliens, and I'm not just talking about such dubiously human individuals as "Snooki." All of us, the article claims, descend from an extraterrestrial race. But how can we prove it?
Well, here's the argument, if I can dignify it with that term.
1) Human babies are born completely unable to take care of themselves, and remain that way for a long time. By comparison, other primate babies, despite similar gestation periods, develop much more rapidly.
2) In a lower gravitational pull, humans could fall down without hurting themselves, "just like a cat or a dog."
3) Humans have biological clocks, and in the absence of exposure to the external day/night cycle, they come unlocked from "real time" and become free-running. So, clearly we came from a planet that had a different rotational period.
4) Humans don't have much body hair. At least most of us don't, although I do recall once going swimming and seeing a guy who had so much back hair that he could have singlehandedly given rise to 80% of the Bigfoot sightings in the eastern United States.
5) Geneticists have found that all of humanity descends from a common ancestor approximately 350,000 years ago; but the first modern humans didn't exist until 100,000 years ago. So... and this is a direct quote, that I swear I am not making up: "In what part of the universe was he [Homo sapiens] wandering for the remaining 250 thousand years?"
Now, take all of this, and add:
1) Some nonsense about Sirius B and the Dogon tribe, including a bizarre contention that the Sun and Sirius once formed a double-star system, because this "doesn't contradict the laws of celestial mechanics;"
2) The tired old "we only use 3% of our brains" contention;
3) Adam and Eve;
and 4) the ancient Egyptians.
Mix well, and bake for one hour at 350 degrees.
The result, of course, is a lovely hash that contends that we must come from a planet with a mild climate where we could run around naked all the time, not to mention a lower gravitational pull so we could just sort of bounce when we fall down, plenty of natural food to eat, and "no geomagnetic storms." I'm not sure why the last one is important, but it did remind me of all of the "cosmic storms" that the folks in Lost in Space used to run into. And they also came across lots of weird, quasi-human aliens, while they were out there wandering around. So there you are.
In any case, that's today's example of adding 2 + 2 and getting 439. All of this just goes to show that even if you have access to a lot of factual information, not to mention the internet, you still need to know how to put that factual information together in order to get the right answer. For that, you need science, not just a bunch of nutty beliefs, assumptions, and guesses. So, as usual, science FTW.
Which, of course, applies to a good many more situations than just this one, but as I've already given a nod to the Institute for Creation Research, I'll just end here.
