We don't know who first came up with the god idea.
The oldest human fossils (so far) have been found at an open cast mine in Jebel Ighoud, Morocco. The fossils were found along with stone tools and are estimated to be 300,000 years old.
The oldest historical record we have about religion (i.e. something written down) is on a clay tablet from a temple in Nippur in Iraq and it is believed to be about 5,500 years old. The tablet talks about several gods including Nintu, the goddess of creation.
So, we have a gap of about 294,500 years about which we know almost nothing in terms of what people believed.
We can imagine two people, sitting down in their cave, talking about the world and asking questions to which they had no answers.
The world must have been a frightening place when you had little understanding of how it worked.
The animals and plants around them were vitally important for a hunter-gather society - if the weather turned bad, and the animals and plants were in short supply, it would have been devastating for them.
All of us sometimes "wish" for things. We wish the weather was better, we wish our friends were kind to us, we wish we could have more fun. Early humans must have wished for things to make their lives easier - for better weather, for success when hunting, for a new baby to survive etc.
There is a big difference between wishing for something and wishing to something.
We don't know where the idea came from to wish to something - to wish to the sky for the sun to rise, to wish to trees so they would grow fruit, to wish to the sky for it to rain. Wishing to something assumes that the something can hear you and do something about it.
At some time, someone must have come up with the idea that thing they wished to must be able to control things in some way, it must be alive but invisible. This was the beginning of ideas about invisible supernatural spirits and gods - so wishing became worship - praying to the gods.
A "theist" is someone who believes in at least one god and we know that the followers of early religions were "pantheists" - they believed in more than one god. The ancient Egyptians had over 1,400 different gods and goddesses while the ancient Greeks had 12 main gods and goddesses who lived on Mount Olympus. The highest mountain in Greece is today called Mount Olympus - but no one who has climbed it has seen any gods on top (of course, they would be invisible).
The first monotheist religion (belief in a single god) was probably Zoroastrianism which began about 3,000 years ago in Persia - modern Iran. In fact Zoroastrianism has two supernatural gods: the good god Ahura Mazda and the bad god Angra Mainyu. Most religions see the world as a conflict between the good and the bad.
"Theist" leads to "atheist" with the "a" meaning "not". Atheists are not theists, they see no need for the god idea and no evidence for it. Atheists are defined by what they are not, not by what they are - there would be no atheists if there were no theists. This also explains why there is no such thing as "atheism" - atheist don't have a set of beliefs, the only thing they share is that they have no need of the god idea to explain things. Some atheists call themselves "humanists" and they do share a set of moral values and a view of the world - but they don't believe in anything supernatural.
These three things are often muddled up so our definitions are:
When someone uses the word "god" it is always worth asking what exactly they mean. In many cases they use words that are equally difficult to define, like "spirit", "ruler of the Universe" and "supreme being". Those are not definitions, they are labels.
Belief is required for things like "god" - because it can't be proved in the normal way we talk about proof in logic, maths and science.
Many religious people claim that the existence of a god (or gods) can be proved - and people have argued about this for the last 3,000+ years! We have a page covering the classic god arguments.
"Belief" should never be confused with "truth".
Something is "true" if we have evidence and proof for it. For example, it is true that we will all die sometime, that 2 + 2 = 4 (in base 10) and that water is made up of oxygen and hydrogen.
Something cannot be "true" for one person and not true for another. It is either true or not true.
People disagree about the god idea, some people believe it, others don't. The god idea is not a truth.
It is worth pointing out that there are hundreds of different god ideas. Even those people who share the same god idea, and the same religion, may have different interpretations of their holy books - so there are hundreds, perhaps thousands, of different religious groups (called "sects"), each differing slightly from the rest.
There are many people who claim to believe the god idea because they have no other explanation for why things are as they are and perhaps they have a fear of death, but they don't claim to follow any religion. Many of them are embarrassed by things done in the name of religion so they prefer to keep their beliefs private.
We have more about religion below.
Tabula rasa is a very useful idea which comes from the Latin language and means "a clean slate" or a "fresh start". The idea is to look at everything with an open mind, without any assumptions or beliefs that may alter how you see things.
Every baby is a tabula rasa, it is a clean slate, it is not born believing in a god or as a member of a religion. There is no gene for Christianity, Hinduism, Islam, Judaism, Zoroastrianism, etc. so there are no Christian, Hindu, Muslim, Judaist or Zoroastrian babies - only religious parents.
We are all born believing in nothing but many of us have our beliefs imposed on us by parents, family, friends, teachers and community. Some of us investigate further and make up our own minds.
Another way of thinking about it is to imagine you are a visitor from a planet in another star system. On your planet you don't have gods and religions but you want to understand why they exist on Earth. So, you have a tabula rasa as far as gods and religions are concerned - you are starting from fresh.
We would like to introduce you to one of our favourite people: William of Occam. We are big fans of Occam!
William was around in the 13th and 14th centuries - somewhere between 1287 and 1347 - and we think he was born in the village of Ockham in Surrey. He is usually called "William of Occam" rather than "William of Ockham" - names often change over time.
Like most people of his time, William was religious - in fact he was a Franciscan Friar - a type of religious priest.
You may find it strange that a religious priest is one of our favourite people, but, like many religious people at the time, William wanted to think for himself and not simply believe what he was told.
William came up with a brilliant idea to use when finding solutions to problems. It involves getting rid of, or shaving off, all parts of an idea that aren't absolutely necessary to explain something. The idea of shaving things off is why William's idea is called "Occam's Razor".
We love that! Some of us write computer software and we use Occam's Razor every day to keep things simple.
Occam is recommending that we start with a tabula rasa so we can make a fresh start when looking at anything.
Before we start we would like to correct something you may have been told. You have probably been told that "atheists don't believe in a god".
The person writing this page is an atheist and gets very upset about this.
Lots of people don't believe in lots of things but we don't have to label them as "afairyists" if they don't believe in fairies, or "aunicornists" of they don't believe in unicorns or "ahobbitists" if they don't believe in hobbits - that would be silly.
Theists invented the god idea so they are the ones who have to prove it. Atheists haven't invented anything (about religion) so we don't have anything to prove.
That's how we prefer to be defined: "Atheists see no need for the god idea and no evidence for it."
We need some ground rules when we start with a tabula rasa:
Before you accept a new idea you should ask:
Did you notice how we referred to god as "she" and "her"?
Why do people almost always refer to their god as "he"?
Should a god be "he", "she" or "it"?
Is a god male or female - if so, why?
Please don't say "because it says so in our holy book" - holy books were written by men!
Why don't we hear much about miracles today?
In the past people couldn't read and they weren't well educated. Could it be that more people today are willing to ask questions and look for simpler explanations?
For a really hard question, try asking a religious person: "what exactly is a god?"
Religious leaders often lead "prayers" where religious people thank their god for things or ask their god for things.
A split in a religion is called a "schism" - pronounced "skism".
"I think it means this, you think it means that."
which is usually followed by:
"I am right, you are wrong."
which, in the past, was sometimes followed by:
"and I will kill you or imprison you if you disagree with me."
It is always followed by a schism as a new sect pops into existence out of nowhere.
The answer is usually:
"my sect is right, your sect is wrong."
Maybe they are all wrong?
Maybe we don't need the god idea at all? (We atheists don't need it.)
Maybe the world would be a happier place without religions? (We atheists are happy without religion.)
Maybe there are other reasons why people join religions? (Family, friends or the social life.)
