How old do you need to be to create video games

You can really start whenever you want, but it depends on how serious you are.
If you are just beginning, try Scratch. It's like programming with Legos.
If you are a little more serious, try Visual Basic or GameMaker.
If you can already program with something like C or Python, then you are pretty much ready for serious video game production.
Now if you are asking about how old you need to be to be employed, then it is almost guaranteed you will need to be at least 18. You would probably start out as a game tester, then just move up from there.
Some 3rd parties that provide game testing for other companies may allow part time jobs, so check with your state's Department of Labor to find out the minimum age for work.
Recommend a record tool - PCHand Screen Recorder, it could record any activities on the screen and the audio of whatever you hear. I tried a lot before buying, it's easier to use. It also provides a free trial version. You should try it. I'm using it and it's pretty good...
