What do we call to someone who believes that God does not exists? [closed]

We know there are differences between,

  1. One who disbelieves/denies that God does exist
  2. One who believes/accepts that God does not exist

Now Dictionary.com defines the term atheist as

atheist [ey-thee-ist]: a person who denies or disbelieves the existence of a supreme being or beings.

So, what do we call someone who believes that God does not exist? Is there any such word in english?

Note: The question came to my mind because, a person disbelieving on a premise does not necessarily need to believe on the opposite of that premise right? For example, in the above mentioned premises, someone who denies that god exists can be agnostic (a person who believes that nothing is known or can be known of the existence or nature of God) as well. But someone who believes god does not exist can not be an agnostic.


Solution 1:

According to the Cambridge dictionary, atheism is:

the belief that God does not exist.

An atheist is somebody who subscribes to atheism; thus the word you are looking for is atheist.

On a higher level, in English, most people consider that disbelief in something is equivalent to belief in its opposite. This is known as the principle of the excluded middle, and its status as a logical principle goes back to Aristotle. There are a few philosophers and mathematicians who do not believe in it, but these are a very small minority.

Possibly in your native language, disbelief and belief mean different things than they do in English. But the only English words I can think of that might be answers to your questions are agnostic and atheist.

Solution 2:

Atheist [ey-thee-ist]

A dictionary goes 'a person who disbelieves or lacks belief in the existence of God or gods'. Stephen Hawking was an atheist, who never believed in the existence of God.
