The Universe is only about 6 months old. God created it whole, including false memories of our past and conditions that would indicate that the universe was much older. Why? Because he’s God. He can do these things. 
Sure, but why bother? The universe is 14 billion years old or it’s five minutes old and he just made it look 14 billion years old. Makes no difference to us; makes no difference to him.
I think the OP is more likely to be right, as 28028 BC was an Olympic year, and some of the earliest artefacts we’ve found of modern humans are clay discuses.
The one holding the joint is always right.
I’ve read the some sort of humans popped up at different times around the world. But they went extinct somehow so maybe they both are right.
Julian or Gregorian?
Now, was it a formal appearance or a casual appearance? In short, were tuxedos and formal gowns involved? Because that could change the date radically!
Is it possible that the OP’s friend’s number (237629 (BC)) was actually a (mis-interpreted) Star Date?
Bingo. It doesn’t bother me so much that the dinosaurs never existed, but it seems sad that the hot chick I knew 30 years ago was just an illusion.
Appeared? Where – on a stage maybe?
What pisses me off is god couldn’t be bothered to add to the illusion that I banged her.
