And so where did Jesus come in here? 2000 years ago. About 8000 years after "modern man". Nice supernatural story. Has some, ok, values.

Show me a planet in a solar system anywhere else with the diversity of life forms and the climate, water, and atmosphere to sustain it. If the "invisible man" didn't actually put us here, then I'd guess he supplied the ingredients. I sure as hell hope that this isn't an accident.

From what I've read in the Bible, it sure doesn't look like God does.

Anyway, sure was nice of Fossil_digger to post this neat chart up, huh? Cool.

Yea cool chart. It show the vastness of what man knows, and it should show how insignificant mankind is. Shure we are also destroying this planet in a matter of centuries, LOOK HOW FAR THE CHART GOES BACK. Time has been going on FOREVER, AN INFINATE amout of time, and it will continue on, regardless of "mankinds" state.

In my last moments I'd give 200% (i know it's impossible, but you get it) to privent my death. Because when you die, you lost the game of life. Life is all you have. Afterlife? Nice thought. Christianity has too many flaws. My last words have almost been, and probably be "shit" or "fuck". NICE CHART CHRISTIANS CAN'T EVEN FATHOM.

reality, what a concept! science and religion will never coexist. but one things for sure; noone will sway my thinking w/o scientific facts. religious myth and legend are not fact in my book. i have to have factual proof. nothing i've ever seen can substantiate anything in any religion can provide.

ninepointfiver@79212 : so, just out of curiosity, what personal experience do you have with the after life?

I would disagree with you fossil, they can coexists: spirituality can give a person the answer to 'why' we are here, whereas science is the 'how'. It also helps to give meaning in life, at least to some. It does also reiterate a moral code, which can be helpful. Basically, "Do unto others..." , and "Happiness through altruism". Although, those last are attainable from many sources.

John, I haven't any experiences with the after life. It's all based on faith. That was my point, if you don't beleive, you'd better hope your right. I'm not trying to preach, it's just a thought.

I think that's pretty much how I feel, John.
Science and religion can co-exist. The world around us is so vast in its complexity, and so much of it goes well beyond our knowledge and comprehension. I think we would be pretty damn arrogant and shortsighted to think we can come up with a scientific explanation for everything.
fossil_digger Report This Comment

but there is an explanation for everything.....you just have to substantiate your evidence. some things are more easily proven than others. archaeologists have to make assumptions based on fact, along w/ paleontologists. but at least there are facts available, if you know how to look. religion is tied to history. depending on who you ask. religions only apply what they want to substantiate their own beliefs. do whatever makes you happy, cause happiness is the only (well almost) thing that counts.

"All belief makes us insolent; newly acquired, it inspires the worst intincts; people who do not share it appear eithyer impotent or vanquished, deserving only pity and scorn. Consider the neophytes in politics and especially religion, all those who have managed to interest God in their arrangements, the converts, the /nouveaux/ /riches/ of the Absolute. Compare their impertinence with the modesty and ghte good manners of those who are in the process of losing their faith and their convictions..." -- E.M. Cioran

Personally, I don't think these quotes have anything relevant to say about why we're here.
I'd like to think that my life is something more than accidental. All of us have a purpose, whatever that may be.

i found a really good philosophy site, drop this off and search more."The world is a teeming mishmash of cultures with a bewildering array of values and ideologies engaged in their own version of the good life. People are generally not interested in changing the metaphors through which they view the world, so real understanding between groups with conflicting viewpoints is not achievable in the short term. The good news is, that's OK, because the world isn't supposed to be saved on a global scale. It must be saved at the level of the individual. And despite the fact that the level of the individual appears to be statistically insignificant, it is in fact the most significant, because it is only at the level of the individual that a creative synthesis of conflicting metaphors can occur. Once a connection is made at the individual level, the process of spreading successful new metaphors throughout society is essential automatic if the society is ready for them. If the society is not ready, the new metaphors will not be accepted under any circumstances. So don't beat you head on a rock. Solve your own interpersonal communication problems. If the world is ready to benefit from your solutions, you will not be able to stop it from using them."
