How does this new finding challenge previous theories concerning the role of asteroid impacts in delivering water to Earth?

The study challenges the long-held belief that Earth's water originated solely from asteroid impacts. The discovery of intrinsic hydrogen in a 4.6-billion-year-old meteorite, similar in composition to early Earth, suggests that sufficient hydrogen and oxygen existed within Earth for water formation from its inception. This indicates that water on Earth may be an inherent, rather than a coincidental, characteristic.
