My god....I never actually thought about this until right....now.....and it hurts my brain. To think...there was a time, with no life - just chemical reactions, and elements, and chaos. And out of that somehow arose living things with the "desire", or need to replicate and multiply. How many trillions of things could of gone wrong in that primordial soup to prevent any of this from happening: life, us, civilisation. Scary stuff.
Anyway, here's one way of looking at it. Everything alive must have descended from the same organism right? And that organism's only purpose was to replicate. Over the (millions of) years evolution gave the organism senses, and abilities to help ensure that replication would take place, by creating countless variations on the organism (through random mutations, natural selection, whatever). So we're just the most advanced variation of a very simply life form. Our senses, our intelligence, our self awareness (everything we pride as making us...us) are here because they give us the edge; they equip us for survival, ensuring the replication of "the life form". We think, and feel, because we have complex extensions to our basic senses that allow us to interpret our surrounding, and situations better. Every emotion and feeling can be stripped down to a primal instinct, and every primal instinct can be linked back to a sense, or some sort of "feedback" that the body relies on for one reason or another. SO....given all that...perhaps we're just a vehicle for a very very simply organism; we're slaves to it! We reproduce because it wants us to. Ooooh scary. lol
Well I dunno. I'm no scientist. I only got a double B award. And that's a very cold way of looking at life - it was just a random thought I had just now. Probably completely *******s though. I think considering everything we've yet to understand, it's entirely plausable that some "spirit" does reside in the human body. And I don't mean spirit in the mumbo jumbo way. I mean perhaps consciousness (i cant spell that word) resides as a more complex network of matter outside of our range of perception or something. Or it occupies our space (or another form of space) in such a way that it cannot yet be measured or observed. Who knows.
I don't think we're meant to find out though. you know how the journey to somewhere is usually alot more rewarding then actually getting there? Life is like that I guess. The fact that we all have that deep routed instinct to know why we're here is what makes us feel alive, and like we have purpose in a very cold and bleak universe. But were we to be able to actually say "this is the purpose for our existence; this is why we're here"....we'd probably be very dissapointed with what we found, and what would be the drive or the motivation to carry on...living!?
Sorry, this is long. Just some things for you all to think about. Feel free to mock my unique brand of pseudo science, incorrect terminology, and half-baked concepts.
