ELI5: Why is Anakin Skywalker so powerful? Does he have an origin story, or is it supposed to be left up to the viewer's interpretation?

I know from episode 1 that he came from a virgin birth. He has an uncanny connection with the force. And he is basically assumed to be potentially the most powerful dude ever. My question is did Lucas or any fan theorists ever predict why this is?

They go into it more in the EU, but the movies kind of tell their own (different) version without as much detail.

Qui Gon worshipped "the living force", and believed in a prophesy which said that a special individual would come to "bring balance to the force". The movies say that Anakin was a virgin birth, brought to life by the Force itself.

Now most of the Jedi assumed that this meant he would be the one to wipe out the Sith. Obi Wan even says as much when he's about to fight Anakin.

But if you look at it from a strictly literal point of view... there were dozens or even hundreds of Jedi, and only two Sith. After Anakin and Palpatine killed everyone, there were a couple of Jedi hiding out and a couple of Sith. There was a nearly perfect balance.
