Me as a person observe human's model of the world. My dog if he would be little more intelligent, he would observe the world similary, because we are long relatives (life tree) and his observation and physics laws would be similar to our I gues with some problem with writing and stuff. But What about aliens? If they would not be relatives to earth's life, what would the laws looks like? For example if a virus was not related to life tree and has some inteligence and it tried to describes it's model of the world by using it's own theories and aproaches? Are we so blinded our bodies to create these model based on our percieved reality?
