How did my father find my YouTube channel?

Hey The question may sound a bit silly, but how did my father find my old channel? Context, I haven't told anyone except my classmates about it, and my father lives somewhere in the world, so of course he couldn't have noticed that. You only heard my voice on the channel but never saw my face and the channel name was not related to my name or other private information. It was a would-be Minecraft channel, I was pretty young. But I doubt that he watches the kind of videos, especially those with somehow seven clicks. So how did he get it? That same week. I ask because I want to start a new channel now, I've changed my channel name and would like to make animation videos (in which you can't even hear my voice), but I really don't want my father to know.

If he knows your gmail, it is not difficult to find your YT channel

Or he looks at what you google on the internet and finds out for yourself that it is not difficult…

He's probably signed in with your Gmail

How do you know that your father knows the channel?

I now have a new email address, does that mean that he can no longer find it? But it is still the same Google + account, only with a different name and a new email.

He doesn't know my email address and my password… And I would know if someone else was in my account, right?

At that time he wrote to my mother about it. But that was years ago.

If you don't have your own internet, they can still look up what you're doing.

But he doesn't live with us, but somewhere far away. I don't even know which country anymore.

If he doesn't know the internet password, then it shouldn't be a problem.

Okay thanks!
