Research leads to an idea that Earth became a planet containing water by means of an asteroid composed of ice colliding with our world. Other articles or research state that there were many of these asteroids raining towards Earth from the outer solar system and our Earth formed within the inner part of our solar system at the start of the formation of the planet. At this early stage the planetary materials were burning hot and water would have been unlikely to have been present in the formation due to the intense heat of the sun.
This is the generally accepted idea about the water of our world and its presence, and how it came to be so, however, researchers in Denmark have researched the likelihood of water being present in the early formation of our planet and our two closest neighbouring planets, Venus and Mars. The research suggests that there may be much more of a vast number of planets within our galaxy and a great many may be worlds of water.
Now, take a look at the image here:-
This artist impression of another world shows what looks like ice on mountains. If the ice is frozen H2O (water), then this would mean that H2O may have also been a molecule that formed in the solar system of this picture. Are we though, taking H2O presence or formation and the idea of it for granted?
The world in this picture has something so very strikingly like Earth and some other planets in our system...... rockiness. It is possible that many other worlds that may be out there are much, much, more gaseous or planets of more fluids or a different kind of possible viscosity between solids and liquids or a bridge of our usual idea between these two. There may be liquids out there in abundance on other worlds that have properties like water or otherwise unlike water but with uniqueness of the kind water has.
Life has formed in our world from the matter that our planet is composed of. So the solids, gases and liquids as we know them here on Earth have generated what we know to be life. If this can occur from this concoction of materials and matter, doesn't it seem like a real possibility that this kind of phenomenon may occur in strange alternate ways in the universe and even in many various ways here in our home galaxy?
We talk of a possible prospect of alien contact or finding intelligence out there, but we must expand our ideas of the possibilities and broaden our comprehension to acknowledge the very possibility that the water we have in our system is a clue to help us think about what other unique wonderful molecular liquids or gases there may be in other systems that have helped to form life but not quite as we know it.
We should also think about the prospect of intelligent entire worlds rather than just entities living on the surface. If we broaden our ideas and stay on the lookout for more and more possibilities, we could come up with an amazing way to detect life out there, but not life as we know it.
