In the beginning, God created the bit. And the bit was a zero; nothing.
On the first day, He toggled the 0 to 1, and the Universe was. (In those
days, bootstrap loaders were simple, and "active low" signals didn't yet
exist.)
On the second day, God's boss wanted a demo, and tried to read the bit.
This being volatile memory, the bit reverted to a 0. And the universe
wasn't.
God learned the importance of backups and memory refresh, and spent the
rest of the day ( and his first all-nighter ) reconstructing the universe.
On the third day, the bit cried "Oh, Lord! If you exist, give me a sign!"
And God created rev 2.0 of the bit, even better than the original prototype.
Those in Universe Marketing immediately realized the the "new and
improved" wouldn't do justice to such a grand and glorious creation. And
so it was dubbed the Most Significant Bit, or the Sign bit. Many bits
followed, but only one was so honored.
On the fourth day, God created a simple ALU with 'add' and 'logical shift'
instructions. And the original bit discovered that by performing a
single shift instruction, it could become the Most Significant Bit.
And God realized the importance of computer security.
On the fifth day, God created the first mid-life kicker, rev 2.0 of
the ALU, with wonderful features, and said "Screw that add and shift
stuff. Go forth and multiply." And God saw that it was good.
On the sixth day, God got a bit overconfident, and invented pipelines,
register hazards, optimizing compilers, crosstalk, restartable
instructions, microinterrupts, race conditions, and propagation delays.
Historians have used this to convincingly argue that the sixth day must
have been a Monday.
On the seventh day, an engineering change introduced UNIX into the Universe,
and it hasn't worked right since.
