It's not fictional, this happened. But you're right, it probably happened in 2010, not 2009. I didn't solo mine, but on a pool.

2009 was when I created the wallet. I know this because it was when I received the first email on my current e-mail address. This e-mail superseded the one I saved the wallet keys on.

And chill, dude, I'm not claiming to be a seasoned Bitcoin enthusiast. I played with it in the very beginning, forgot about it, LOLed when people started hyping in 2017, then got into Monero around 2019.
