TTT...all religions are invented, always from highly suspect sources. Look at Scientology for instance ! As these religions are based on such rocky foundations, its no wonder that they are all insecure.
Milvus...us atheists are devoid of belief...that is what an atheist is ! Its up to people like you to justify why you believe in irrational things, not us to justify why we don't. If I stood up at a dinner party and said that Unicorns were real, I would expect everybody else to ask me to justify why I thought that, not for them to try demonstrate why Unicorns don't exist.
If you and others want to believe in this sort of thing, go ahead...just don't expect others to fall for it as well.
Of course, if it was only that easy ! The world is full of people dying because they believe in the "wrong" religion...a cursory glance at the Middle East will confirm that. Religion just breeds malcontent and bigotry...nothing more.
You see, all theists have one glaring fault. By the very nature of their belief, every other religion must therefore be wrong !
