Agnostic
Definition 1 of 4
Pro Tip 1/2
Uncertain Belief
Use 'agnostic' to express lack of certainty in beliefs, not just indecision. After much thought, I remain agnostic about the existence of an afterlife.
Pro Tip 2/2
Open to Evidence
'Agnostic' suggests a person is open to changing their view if evidence arises. I am agnostic about flying saucers -- show me proof, and I will believe.
