Here are the arguments sorted into their respective categories:
Evidence for:
- Spacecraft have confirmed that objects from the Kuiper Belt have Earth-like water.
- Others like it in the galaxy have water in their dust and gases.
Evidence against:
- Very little water is found on/in these objects.
- Spacecraft have confirmed that objects from the Oort Cloud have non-Earth-like water.
- The sun could have evaporated the water over the billions of years since Earth’s formation.
Note: The statements related to "Comets," "Asteroids," and "Solar Nebula" serve as types of objects or origin theories rather than specific arguments, so they don't fit directly into the categories without a specific context. If the question was specifically about those items, you could attach the relevant arguments for and against them accordingly.
