silly,
quesiton=why, not how do we know
ive throught about this for a while. if you look into creation science you will find that there is a very small possibility that humans, animals, life can be created by chance.
then i consider how many other ways could a universe be constructed. we live in 3 spatial dimensions, one continual dimension of time, and we all have conciousness, an estimation dimension within our mind that is similar to the real one.
it seems to me that there is a god or something 'steering' creation. this is the best possible explination if you agree to the size of the possiblility of our existence is as small as it seems.
my friends showed me the profoundness that is life.
regardless of how we came to be, we still are complex chemical reactions, made up of the materials of the planet, the materials of the universe. we are just matter, but we realize this. "The universe becomes concious of itself" becomes aware of itself, understands itself. we are talking rocks.
before animals and life there was th universe,
then the universe became concious.
if someone were to mix some antimatter and detonate it to make a universe, it is possible that they were aiming to distill some conciousness. or possibly whatever we create with our conciousness; creativity, or other answers.
thats by best attempt at an answer.
circular reasoning is a logical fallacy (stupidity) where the question is used as part of the answer. exemplified with life, in that: most everything we do is to become better at what we do, and to create and preserve life so that life may keep continuing.......existence doesnt make sense. exept for trying to find it anyway
