How would I create an entire fantasy world, from scratch?

This might seem a bit of a silly question, as the obvious answer is with your brain, but I was just wondering if there’s, like, websites and stuff I can use to help me create a fantasy world? I’ve been watching a lot of worldbuilding videos, and I’m thinking about taking on a project of my own. But I don’t really know where to start. Any tips? <br><br>Edit: I think that I may have accidentally posted this in the wrong place, so please bear that in mind while viewing this post. For some reason, the worldbuilding community doesn’t allow new members to post here, and I wasn’t allowed to post this in the metatalk sub.
