If god/s are not beings on the Earth, how are we to objectively know there is one or more gods?

Do we have a good notion of god/s?

Have we seen god/s with our space probes?

Is god/s phenomena or Person/s?

Is the divine scope the Solar System, the galaxy, the universe, the multi-verse, a given set of dimensions or a different set of dimensions?

Is god/s interested in religion and worship or not?

The above questions are good reasons to say, I don’t know; therefore, I am agnostic.
