It's my opinion that science of any kind can't be used to disprove or prove the existence of gods. Science is for finding out about the natural world and universe we inhabit, and for discovering ways to put that knowledge to use. If there's a god outside of that, then it's outside, where we cannot look, since we are pretty well confined to the known universe.
Creationism is so rare in my country, and so extremely rare in my end of it, that I've hardly ever met a creationist. Creationists are figments from afar, flittering across my monitor, fantastical figures dispensing fanciful fictions. (Hmm.Ran outta 'fs')
I'd have to combine the reasons in this poll for my agnostic atheism: personal and logical. Evolution had nothing whatsoever to do with it.
hulday153 says: "Evolution is not atheistic. Atheists cling to the theory because their worldview would be shattered by the alternative explanation; but their pro-abortion, pro-gay ideologies should be rejected on the Darwinian principles they claim to embrace. "
This is like me saying all Christian preachers are child molesters because some Catholic priests are. There are homophobic atheists. I know a few. There are anti-abortion atheists. I know a few of them, as well.
Darwin's principles were the foundation of evolutionary science. They aren't some kind of moral framework to be 'embraced'. Do people 'embrace' Newtonian principles as a set of moral guides?
That said, neither abortion nor homosexuality are 'anti-Darwinian', or rather, neither conflicts in any manner with what we know of evolution. There are any number of possible evolutionary advantages to a population having a percentage of homosexual members, and there are similar advantages to having the ability to abort fetuses.
Hypothetically:
Homosexual tribe members who may choose not to mate and bear children have more time to contribute to the family or tribe, by hunting or gathering for longer spaces of time, or by spending more time making tools, containers, medicines. That could be a real advantage for a small group of hunter-gatherers.
There are mammals (such as rabbits) which experience adsorption - their body absorbs already existing embryos or fetuses when the animal percieves the time is not right, food may be scarce. Other mammals, in the same conditions, eat their young at birth. Human women, if they are starving, often stop menstruating, and become less likely to conceive or to have an embryo implant successfully. Aborting when the time is not right is an evolutionary advantage, no matter how it is accomplished.
