I've always accepted the existence of religion. For some people, believing in a higher power is the only thing that makes their life even remotely bearable, and there's also the fact that Science has proven us to be so small and insignificant that I can definitely see some people take Lovecraft's stance on the matter and just run the other way, screaming "Heretics!" all the while. Committing to the idea that there's no God and that there never will be requires just as much a leap of faith as believing in God does, if not more.
The irony is, of course, that the "leap of faith" being used here equals testing and trusting in your own moral principles and your skills to be able to maintain a sense of relevance, reward and purpose in the absence of some sort of omnipotent power capable of smiting the wicked and rewarding the just.
That said, I don't understand people who get offended about the mention of God as an unsound theory in a thread about unsound theories. As I've made it clear above, you've got every right in the world to believe in God. Belief, however, is not proof. Science concerns itself with proof and has the ability to adapt itself to what has been proven or disproved. Considering this, the only way you could get me to believe in God is if you factually proved me that God exists, using empirical evidence. The Bible simply doesn't count, as it, like every other religious text in existence, was written by human hands, for use by other humans.
Belief, however, is only as malleable as the believer can be. Someone with a relaxed stance on Christianity can and will accept that the Earth is several billion years old and that we'll never be able to geographically pinpoint the Garden of Eden. Someone with a hard-lined stance will be inflexible and, when countered, will be at a loss for options.
What happens, when hard-liners are stumped? They repeat themselves, only louder. If that doesn't work, the insults come out. Case in point, the Westboro Baptist Community.
So, honestly, while the first reply could've been handled with a bit more tact, believers claiming to be offended because someone dared to post a comment belittling God are acting a bit out of their depth. God will always and forever will be up for grabs and open to criticism as a mythological figure and concept.
That said? Jeeze. There's a ton of stuff that feels patently ridiculous. The Time Cube theory's already been mentioned a few times, but it's entertaining as all Hell. The idea that the world is controlled by lizard-folk always reminds me of "Conan the Adventurer" and of how Rath-Amon and his cronies were all serpent-men in disguise - and then there's the current guff about the Mayan calendar and 2012.
The Mayans were actually pretty smart, seeing as they made calendars that were designed to last *thousands* of years. Yet here we are, wasting paper every damn year to print another set of calendars and yearly agendas... The Mayan Fifth World ends in 2012, that much is true, but this whole nonsense really comes from Western society's tendency to interpret the term "End" as being complete and all-encompassing.
I just don't get it. If it's so easy to go about ranting the end of the world when we've scientifically proven that the sun has enough juice left in it for several billion more years, what's keeping us from developing a religious system where the end of the world happens every night?
That'd be pretty cool, wouldn't it? "Oh God, no! Look, the sun is setting! Look everyone; the sun is setting! Lock yourselves in and pray! Pray that the Lord will make another day for us to enjoy! PRAY, DAMN YOU!"
Although, my personal favourite would probably be the LHC-induced black hole nonsense. The densest thing to come out of the LHC was quark-gluon plasma, not some potentially world-consuming void. Not to mention that even if micro black holes did form, their size would make them collapse in on themselves eventually.
