Aliens, we always think about. How will they look like, how will they work, how will be the system of life in them. I simply can imagine as I am always a fan of aliens movies. But this is not like simple Jadoo-Krishh theory but it really relates with the MIB phenomenon.
This phenomenon is actually gives us a wide vision to look for the invisible.The way of life origination is always in a cell which may be in a shape of circle (circle because it's the most prominent structure in nature) which has some constituents as minerals and some alchemist matter. This phenomenon explains that we are a part of a big world and there may be some more big worlds too like us in which there may be some more powerful creatures like us or may be differrent than us(that may be imagined in the world of galaxies).Now what this theory try to figure out is that the whole number of worlds (or galaxies) are nothing but a playing pabbles for some other bigger worlds and the players may be the part of their world which itself is a big pabble for the living worlds that is invisible to us.
I had a curiousity about that world from my childhood when i could not figure out the difference between a moon and earth.
