this is getting WWWWWWWWWWWWWWAAAAAAAAAAAYYYYYY off topic: there should be a seperate thread for a 'religion vs. science' debate.
anyway, i dont believe science has created the bomb, or nuclear missiles, or any war-like machinery. it was merely human exploitation of the information and theory science has obtained. human greed lead to the bomb, or nuclear missiles, tanks, guns, etc...
anyway, science in essense is about understanding, to question, to examine, to make judgement on our lives and the world around us. it just so happens that humans have used this information for their betterment --> and at a cost as well. including humans.
from memory, i think marie curie was constantly exposed to nuclear radiation when she was studying radioactive elements, so that we could understand them better. that is a human cost.
remember, we always must learn from mistakes. human cost is just one of those mistakes, and through experience, and learning from those mistakes, we improve and we are more cautious, leading to a better quality of life. if it wasnt for the "millions of people" as HotShot said, we wouldnt have the quality of life that we have today.
this doesnt disguise the fact that religion itself has caused many millions of deaths as well. think crusades, think jihads, think inquisitions, think witch hunts, think protestant vs. catholic wars, think the gulf war, iraq war, think terrorist attacks. many many have died because they didnt conform to a certain religion. think about protestants vs. catholic --> both denominations are so similar, yet people still fight over small small differences.
more to come...
