The word agnosticism was first publicly coined in 1869 at a meeting of the Metaphysical Society in London by T.H. Huxley, a British biologist and champion of the Darwinian theory of evolution. He coined it as a suitable label for his own position.

What is the root of agnostic?

Etymology. Agnostic (from Ancient Greek ἀ- (a-) 'without', and γνῶσις (gnōsis) 'knowledge') was used by Thomas Henry Huxley in a speech at a meeting of the Metaphysical Society in 1869 to describe his philosophy, which rejects all claims of spiritual or mystical knowledge.

Do agnostics believe in God?

Atheism is the doctrine or belief that there is no god. However, an agnostic neither believes nor disbelieves in a god or religious doctrine. Agnostics assert that it's impossible for human beings to know anything about how the universe was created and whether or not divine beings exist.
