Happy Fake Birthday, Earth!
As Skepchick’s (sometimes) resident geologist, I just wanted to wish Earth a happy fake birthday!
According to the most famous of the biblical chronologies, the Ussher Chronology, the Earth was created by God on the evening of October 23rd, 4004 BC. So, that means that today is Earth’s birthday!
Of course, it is a fake birthday since the Earth is really 4.5 BILLION years old and was formed over millions of years, not in a single day. But it is sort of fun to have a day to celebrate the Earth and its age, which is an extraordinary BILLIONS OF YEARS, not a mere 6,013…
One of the biggest challenges of being a geologist is thinking on such long, grand, geologic timescales. Geologists often talk about “young” rocks that are a million years old. A rock that is only 6,000 years old is considered very young indeed… geologists would call such a rock a “recent” or “modern” deposit.
Still, as a human I operate on human timescales of decades, years, and days. So, it is nice to have a day to appreciate the Earth, even if it is biblical bullsh*t.
Happy Earth day, everyone!
Wait. The Earth was created on Mole Day?
Actually, Evelyn, as Ussher was working within the old Julian calendar system, you have to convert his date into the Gregorian system we use today. When you do, you find out that, by our currrent method of reckoning, his date would be Sept. 21st, 4004BCE. So, today is the double fake Earth’s Birthday.
Plittle coulda/shoulda posted this earlier, before I hugged some dirt. And you know, cats don’t have any respect for ecology. Yeech!
Wouldn’t the 6000 years be enough for the wobble of the Earth’s axis to move the equinox around? So Ussher’s calculations, which were related to the equinox, would have to be adjusted for that?
OK, so the Earth was born on October 23rd, … 4.5 billion years ago.

My son was very excited about this news, because October 23rd is his birthday, too!
He was even more excited when a friend of his told him there are 69 more days left in the year.

Yeah, reminded me of a discussion I had with my sister in which she mentioned that very soon the Canary Islands would fall into the ocean and take out, I want to say, the western seaboard of the U.S. I responded with, well I guess I won’t be moving there, only for her to point out that “very soon” meant 10-12 thousand years from now.
Funny, this happens to be my birthday too. But I was *actually* born on that day…
