lets compare this world or universe with ocean, so now ocean means world, here world means our world; air, water, food, humans, animals, plants every thing that you look and feel. now lets assume that water bubble is you. as water bubble is part of ocean as you are part of this world… now lets take a water bubble out from the ocean and its starts floating on surface of the ocean, now this bubble some how after many years starts learning about the ocean, and after few days it learns something and it passes its knowledge to other bubble now other bubble starts learning of new things form the other bubbles knowledge…after few years there where many bubbles on the ocean and they were sharing knowledge from each other about the ocean, now all bubbles where thinking that ocean was made for them coz they need some thing to float, so now they think that some extraordinary bubble has created this ocean for them, that extraordinary bubble is the god. now all of a sudden some thing happens inside the ocean and it kills all the bubbles on the ocean.
… hmmmm so now where is the knowledge which was gathered by all bubbles…?
now ocean is very clam …now who is thinking about the ocean? who is learning about the ocean?who knows there was a bubble which use to float on ocean?
is there anything else learning about the ocean and bubble other than the bubble?
that mean other than human no one in this world knows that what human knows, so once human is dead the world of human will also dies…
