Agnostics do not believe in a God or gods. You quoted from Sagan, who did not believe in a God or gods - to support your version of spirituality and theism....something that was not supported by Carl Sagan
That is your error. My error was not saying atheist instead of agnostic.
Sagan was against hard atheism, not a lack of belief in God. There are hard atheists, soft atheists and agnostics...none believe in God.
It is you who is equivocating. My only error was minor, I should have said agnostic, not that it matters because the result is the same: Sagan did not believe in a God or gods.
