Answer

As mentioned in the [CloudFront API Reference](https://docs.aws.amazon.com/cloudfront/latest/APIReference/API_Origins.html), CloudFront requires at least one origin when you [create](https://docs.aws.amazon.com/cloudfront/latest/APIReference/API_CreateDistribution.html) or [update](https://docs.aws.amazon.com/cloudfront/latest/APIReference/API_UpdateDistribution.html) a distribution, and it doesn't matter whether your origin exists or not.

If you want to delete a non-existing origin, you need to add a new origin first, then delete the old one.
