Ocean Vs Space Exploration

I believe that the ocean should be explored before space. Although both explorations are about finding the unknown we should focus on searching all of the depths orf our planet and gaining the expanse of knowledge form our planet and then use that knowledge to better understand exploration and then apply that to space at the conclusion of sea exploration. The experience gained would help space exploration proceed. So both should be explored we should just start with oceans for the experience factor and about learning the depths of where we live.
