Some of the water got here on comets and asteroids. For some million or so years after the Earth began to form it rained for about a few thousand years.

I am wondering if it is still coming into the atmosphere, thus explaining rising sea levels?

Water is the most abundant element on the planet. There is every argument for the rising an lowering of sea levels but if there is any rise in sea levels from what I know it’s imperceptible at best. It’s not what the climate change doomsday sayers go on about , positing that it happens virtually in a matter of months.
