This long explanation is by Caine Hörr on
a video called "A.J. Jacobs' year of living biblically" on TED.com (I love TED!). I added some commentary in italics.
( Under here. )Philipp Schaub sums it up:
wow, it took some effort to read through all this. Let me paraphrase the story of Jeesus in another way: Humanity's been around for at least 75.000 years. According to your book, Heaven does nothing but to watch - miserable existences, suffering, struggle to survive, I don't need to draw you a picture. Humans almost join the 99.9% of all species that ever lived in going extinct, and Heaven watches.
Then, 2000 years ago, it decides it's time for an intervention. So God comes down to earth and takes action. He doesn't reveal himself in China, where people can read, but the in most primitive part in the middle east. And then he makes his big move to "save" humanity: By offering HUMAN SACRIFICE.
Some story. If there were such a diety, I'd rather go to Hell (where all the interesting people are anyhow) than to worship him for this disgusting display of cruelty.
If you haven't noticed already, I was more or less quoting Chris Hitchens here. He made that point in a debate some time ago.
As for the blowing out candles on your birthday cake thing, it's not exactly irrational if it's fun. Well, actually, I just do it so as not to piss people off when they say they want a picture of it, but whatever....
That aside, most people believe it comes from Greek mythology:
As it turns out, it is believed by many that the Ancient Greeks (who lived in Ancient Greece) put candles on cakes to make them look like the moon.
Said cakes, adorned with candles, were then taken to and sacrificed at the Temple of Artemis the Goddess of the Moon. It was thought that the smoke from the candles carried their hopes and wishes skyward to the Gods. (nj.com)
There is also
this page which says, "History of birthday celebration starts before the rise of Christianity. in some culture it is believed that on the birthday evil spirit visit .It is belief that by creating so much noise is such parties scarce away the spirits." Which is interesting and strange, because then
everyday spirits would be hijacking our world. Usually it's set times, like the transition from Hallows Eve to Hallows Day.
Here is a page with a few explanations on various birthday traditions.
On that note, do people still make wishes when blowing out their candles? I hardly even did it when I was little. I usually just blew out the candles to get it over with,--everyone's staring at me! STOP IT! I never believed they'd come true anyway. *Shrug* Basically,
I did it for everyone else! Isn't it supposed to be
my day?!
I have a habit of making a wish when the clock strikes a time with its numbers all the same though. It's just a habit, but my brain freaks out! Damn you, Catlien. *Fist shake*--She's the one who told me about this, and I always wondered why the hell a wish would come true because all the numbers were the same.
