Truth is revealed to you when one's self is in a deep meditation state. Your senses are working at a minimal, and you do not have thoughts racing through your head. Your mind is back to its earliest form, not even close to our minds now. Now when you are not in a deep meditative state, you can also be asleep. Now since you are primitive man, you are only use to having one first person view, all the time. You do not have imagination yet, because you have just evolved from apes. Your mind is a brand new sponge, never been used. So when you are asleep, and your senses minimal or at rest, your mind has no idea what to do. Since you are a sponge, your dreams will be simple things like you getting food. This is why when animals dreams, for this instance a dog, run in their dreams, because they do not have the minds we have, but their brain and mind still dream when they are sleeping. Why do humans have such an evolved mind? Why don't ALL apes or animals have our minds, they experience things just like us? Humans have such an evolved mind, because we are the most adaptive. Humans populated the planet because we can a) adapt to climate, b) adapt to food source. Let me explain a little more. When the waters go bad, fish and reptiles would be doomed if they were pushed to colder weather. Our bodies are so perfectly built for adapting to climate. We had hair at the time to survive the slight upward migration climate change. We have hands with a working thumb, and we can run and climb. It is easier for us to escape being hunted. Ancient apes started the trend of adapting to food source. Pretty soon, global climate sifts (cause) would shrink the jungle home of the monkeys (effect) This would cause them to switch habitats and adapt to a new way of living. At one point, a group primitive men emerged. They have a change in body, because they were forced to adapt to a new environment. Now they began migrating, possibly searching for food. This is possibly when we could have discovered the ability to eat fish, and once fire was obtained, which would have allowed for new types of food to be consumed.Why is fire so important? The first time lightning made created fire, man didn't just go pick it up and instantly know to put it in some wood. He (they) would have saw it, most likely coward until ONE MAN was brave enough to at least walk next to it. He would have experienced heat and felt warmth, although he would have no idea what the hell it was or what this feeling was. Now, back to my dream topic. Once this homos experienced stuff like fire, they would have a new first person view. It is something out of there norm, it is different from their normal animal instincts. They would dream of this fire many nights, probably having similar dream as the other person. They could start having different dreams because they would have different ideas on how it came to be, because their minds can not truly say. We see lightning, they see flash of something. This could happened several times in wooded areas, which allowed them finally obtain this power. We now have fire, and know its hot on this limb of a tree we still live in, so we will collect more limbs, not branches or sticks because wtf are those words. With fire, we migrated the globe even more, but now we could survive in different caves in different areas, because we know this fire makes our body not shiver. (makes us warm) From there, it is a chain reaction. More adaptation to food, even more brain growth size. This is the start of the minds and brains we have now. Now, what does this all mean? cause and effect are very true. Before we harnessed fire, our universe was run on cause and effect. We are the difference, we broke away from the norm. We have created our own free will. Darwin's evolution theory is completely correct, but "we" were the ones who noticed it, NO other organism on this planet knew they evolved from some primitive organism. Now, here is the start to my opinion of this. This still does not explain how. My idea as of now, since we do not truthfully know how, is that our universe was created by something absolutely perfect; a deity, the "UNIverse", something. (im iffy on that issue). The universe runs on laws of physics, although it does not know this. They are only present when a conscious being notices the "laws of nature." I do believe we have souls, and we either become "one" with the first cause and effect, or our soul goes to another plane of existence. If we truly have free will, a "God" could have possibly given it to us. If that is the case, he started the universe and just let it play out, knowing at least one advanced conscious being like us would turn out. Because without any conscious beings, how would "god" know he exists? sorry, extremely high.
