Are the oceans /seas higher than lands?

Answer 1

depends if land is above or below sea level example holland is below sea level

Answer 2

On average, no - if most of the land was below the seas or oceans, we'd all be swimming.

But there are places that are lower than sea level. One answerer pointed out Holland. Parts of this country are reclaimed sea bottom, where dikes were erected and the water pumped out. Death Valley in California is another spot that lies below sea level.
