How did all the salt in the ocean get there?
gpt
Rain falls on land. Land contains salt which dissolves in the rain. Rain eventually makes it to streams and rivers that eventually lead to the ocean. Water then evaporates from the ocean to become rain again but the salt that was dissolved in the water cannot evaporate so it stays in the ocean.

Rinse repeat for billions of years.
