Question: If any physicist could understand. How were wormholes created?

As far as we know, there aren’t any wormholes, sadly. And we have no idea how to make one (or if making one is possible), so we’re still ways away from creating it! But maybe one of you would be the first person to come up with something 🙂
.
We think that the Universe is “flat”. If you look in two dimensions, let’s say length and width wise, the Universe is a pretty flat sheet of “spacetime” (see the picture below). We can only move on the surface of this sheet; we can’t move up or down. Heavy things like planets and stars cause the spacetime to curve, and black holes cause it to curve A LOT.
.
Well, if the Universe wasn’t actually flat, then maybe at some point this flat sheet would bend around and wrap underneath the sheet where we live. Then, if you poked our sheet through with a black hole, it would go around the other side.
.
That would be a wormhole. We could go in our side, and slide through the wormhole to emerge on the other side – it could otherwise take us eons to get there by just walking along the sheet!
.
But this is just a theory. We don’t have any evidence that the Universe curves like this, so it’s very unlikely to happen naturally. Maybe we could force it to curve, but we don’t know how. And finally, a wormhole is still a black hole – and no one knows what happens when you enter one!
