@firefly,
Quote: If we confine ourselves to the first human word, I'll say it was, "Duh".
As in, "Duh...what just happened? How'd I get here?"
Not true. It turns out the first human was Jewish and her first words...(yeah the first human was a lady)...anywho, her first words were "Oy vey!" as she looked around at the mess that had been made in creating her and knowing she'd have to clean it up before the first man came along and of course have the appropriate foods on the table and the meat and dairy on different plates (a difficult task since plates had yet to be invented).
It's no wonder she said what she said.
So the first word was actually Oy.
