Answer: There is a lot of research on this topic.
According to Kabbalah, water is the quality of Bina, bestowal, and quality of life. And although this is not the force of life itself, life is impossible without it. That is, water is the universal filler, the solvent, the substrate, from which everything grows.
Earth without water is lifeless. Supply some water and there will be life. This life exists not in the water, but in the soil, but without water it is dead. Water is the means to start life.
In our prenatal development we are in water. We are 90% water. And so on.
In the wisdom of Kabbalah, the upper waters and the lower waters are enormous qualities of the worlds. All spiritual space is filled with water. We exist within it. We do not swim somewhere, but we exist inside it, like qualities that are opposite to water, but living precisely because we have received the correct contact with it. That is, our whole life is built inside water, the properties of bestowal.
