Agnosticism is the view that the existence of God, the divine, or the supernatural is not known or knowable with any certainty. If the question is "Does God exist?", "yes" would imply theism, "no" would imply atheism, and "I'm not sure" would imply agnosticism—that God possibly can or cannot exist.

Do agnostics believe in a 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.

What is difference between agnostic and atheist?

Technically, an atheist is someone who doesn't believe in a god, while an agnostic is someone who doesn't believe it's possible to know for sure that a god exists. It's possible to be both—an agnostic atheist doesn't believe but also doesn't think we can ever know whether a god exists.
