So, please give me your best reasons of being an atheist. You may start with the most convincing one.
Thanks.
Guess I'll finally answer the OP more directly (if this is actually what you were asking for). Some reasons for being an atheist, off the top of my head, & in no particular order. Here goes...
- The sheer number of different, conflicting religions worldwide which all have devout followers.
- The fact that we have actually observed the formation of religions recently (scientology, mormonism).
- The large number of past religions which are essentially extinct.
- The many different denominations within a single religion with huge variations between them, all which have their own doctrines, rituals, & of course conflicting beliefs. Each have very devout followers who think they are right & others are wrong.
- Single denominations that have huge disagreements (episcopalians, for example).
- The FACT that religion is largely dependent on where someone is raised & not some "divine" truth.
- Bringing up children to believe christianity is true & everything else is false (brainwashing). Necessary to keep religion alive?
- The many stories in the bible, & especially the old testament, that so strongly conflict with everything we know about the world including history & science. The creation, fall of man, jonah & the whale, the virgin birth of jesus, the flood (why didn't all the fish/marine life die from the change in the water?), etc. These big-time miracles just don't seem to happen anymore. Nowadays "miracles" are hardly discernible from pure chance or coincidence. This is where it all started for me.
- Religion & the "god of the gaps," & religions all-to-often anti-science stances. Some religions siding with science while twisting their doctrines to fit, others denouncing outright those theories which may have theological consequences.
- Religion encourages belief without evidence, or belief with no good reason to believe. That is the essence of faith.
- The many scientific explanations for life's origins, life's variety of species, our earth, the planets, etc., exist & provide solid evidence to back them up (even if religious deniers close their eyes & cover their ears). But just b/c it's difficult for laymen to grasp them or even be aware of them doesn't mean they do not exist.
- The emotional & communal or social attachment to religious organizations & churches. Take this away & quite a bit is lost.
- Manipulation during church services, church camps, etc by emotional music & word-smith pastors. They also often prey on the weak-minded, scared, down-trodden, etc.
- Propagation of fear or scaring people into believing. Hell can be an influential motivator in the prevention of doubt. This fear prevents sound reasoning & questioning & also promotes paranoia w/in believers regarding those who may have different beliefs.
- Outdated/strict rules regarding health, diet, etc. (Kosher foods, for example)
- Religion being pushed in government where it's not welcome & its consequences.
- Divisiveness of religious beliefs, be they inter or intrareligious beliefs.
- Lying for jesus & revising history for jesus (David Barton, for example).
- Lack of evidence for any of the claims made by the religious regarding anything supernatural. (existence of the soul, heaven, hell, prayer more than just talking to yourself, etc.) And no, near death experiences too similar to trips on drugs, dreams, etc. & vary depending on a person's background.
- How gods or goddesses always appear to made in the image of man, not the other way around.
- christians always knowing what god wants even though the same people will claim god cannot be understood or fathomed. What their god "wants" too often coincides with what the person wants.
- No one can answer the question about where or what made god. Sorry, god existing forever outside of space & time or whatever just doesn't cut it. For example, when people believe that something is so complex it must have had a designer (the circulatory system & "irreducible complexity"), yet god (which would have to be more complex than the complex thing it created) is so conveniently not required to meet this requirement.
- Humans being made in the image of god. So does god have male or female anatomy? Or both? Why do most people believe god is a man? What's the purpose of god being a male or female if it can't reproduce sexually? Is god a formless blob? Never heard anything but shuffling & inconsistent answers with this one.
- Inconsistencies & contradictions in the bible. People can't agree on whether it's infallible or not, what's allegory & what's literal. Anyone can make any verse fit any occasion.
- Let's not forget the many versions of the bible.
- God loves us so much that he will torture us for eternity for simply not believing & not groveling. And no, "turn or burn" does not represent a fair choice. (of course, christians can't agree on this.)
- How a god could supposedly fix everything on earth, but waits to see if we will on our own "free will." That is...even though he supposedly already knows everything from the past, present, & future. God must not be that smart or just easily confused.
- Similarities between santa, the easter bunny, etc. to gods & other religious icons.
- The FACT that I can live a moral, happy, fulfilling life while also believing the supernatural is nothing but superstition.
This is just off the top of my head as I'm typing & in no way represents a complete list of reasons.
