Well, that's an interesting situation. Eliminate all of the land and the world's human population will need to find new places to live, grow food, and drink. You've also killed off a huge amount of land-dwelling animals and affected the food chain. However, by "eliminate all of the land", this implies that we're also eliminating the Earth's crust, mantle, and and core. This leaves just the outer core as the outer core is a liquid and technically not "land". So, now, we have massive amounts of salt water, pure drinking water, and outer core just coexisting together and I have no idea what'd happen.

On the other hand, if we "eliminate all of the sea", that's 71% of the Earth's surface now exposed. Mankind will need to find other ways to obtain drinking water, which can be done via mixing hydrogen and oxygen gases and igniting the reaction. However, you've also killed off all fish and water species so a lot of countries will need to find new sources of food. The upside is that you will now be able to transverse the continent on foot, explore shipwrecks and areas never-before-explored by man (and not robot), and mine for minerals.
