We don't generally know how much water is available in most different planets in the universe, yet we have motivation to thoroughly consider there's bounty there for a similar reason that there's bounty here: similar procedures that put water on our planet (the buildup of hydrogen and oxygen into water as the primordial gas cloud falls into a star) will occur somewhere else.

There's really not too much water on Earth. It simply happens to all be at first glance, in light of the fact that the things that make up the main part of the planet (press, silicates, and so forth) tumble to the inside and the water (and in addition gases in the air) buoy to the surface. Contingent upon the temperature of star, separation of the planet, and a group of different components, it can be fluid.

We don't know what number of other water-shrouded planets are out there; we're simply starting to discover them, and recognizing water on a planet a huge number of miles away, in the glare of an adjacent star, is a hell of an accomplishment (however not feasible). However, we evaluate that there are presumably a significant number of them basically in light of the fact that similar procedures that happen here most likely repeat everywhere throughout the world.

There's nothing exceptional about existence that makes that important. It's simply that we, obviously, were conceived in a place that is reasonable to life as we probably am aware it. There are different spots appropriate to life as we probably am aware it, and that is the best place to go looking. There may well be different sorts of life as we don't have any acquaintance with it, however since we don't have any acquaintance with it, we don't recognize what to search for; it's sufficiently hard to discover what we do realize what to search for. So we begin with that and work out from that point.
