There's lots of flowing water in the universe. The presence of water doesn't necessarily lead to life; conversely, life doesn't necessarily need water. Only Earth's life does, and we have no guarantee that life anywhere else in the universe would be even similar.

This isn't necessarily true. We live in a carbon-based universe. It's quite logical to assume that water, which is abundant in the universe, and a pretty simple compound of hydrogen and oxygen, both of which are extremely abundant in the universe, could be a necessary building block or requirement of all life.
