Many comets and asteroids contain water ice, and it is considered that these objects brought a large amount of water to Earth in its early years. ![Where did water come from](https://yourviews.mindstick.com/stories/a57319ed-8db2-4311-8125-fa02a6c2afa0/images/e9d8c07e-ea1d-4c96-a56d-aaeac674679f.jpeg) 2. Some scientists believe that water came from within the planet itself, maybe hydrogen-oxygen interactions in the early atmosphere and magma oceans. ![Where did water come from](https://yourviews.mindstick.com/stories/a57319ed-8db2-4311-8125-fa02a6c2afa0/images/504f7768-ad65-4382-bb97-256a7685c5a3.jpeg) Both theories offer evidence that these objects may have played a part in delivering water to our planet. ![Where did water come from](https://yourviews.mindstick.com/stories/a57319ed-8db2-4311-8125-fa02a6c2afa0/images/190d7d6a-c0d0-41d3-900b-42768d88f4e2.jpeg) It's worth noting that these are just two possibilities, and there's still a lot we don't know regarding the origins of Earth's water.
