Answer:
Ocean exploration is more valuable.
Step-by-step explanation:
Ocean exploration is more valuable in my opinion because it takes place right here on Earth which is the planet we live on. Don't we want to know what is on our own planet? Only 19% of our oceans are explored which is insanely small speaking how the Earth is 70% water. Exploring the ocean would lead to many discoveries and many answers to the worlds most asked questions. Not trying to say that space exploration isn't important but what is the point of exploring space when our own planet has this much of it that is undiscovered.
Hope this helps.
