I personally always found water to be a strange thing. It just so HAPPENS to have a formation that can solve almost anything, is bi-polar, inodore, invisible, and un-tastable (excuse my vocabulary, don't know what the actual words might be.), it also has a PH of 7 (null acidity) and is also an important part to all life on the planet.
Anyone finds that to be way too much coincidence? I think it might have been some extraterrestrial beings that put water on this planet, or might be the only proof of God yet known.
Note this mixes Philosophy, Religion and Science.
