Excuse for horrible actions.

Sky Daddy or his more accurate title of „Fictional Tyrant with bad Temper“

The Big Lie.

"The Biggest Con of All Time"

• Random Chance

I think, otherwise, the only time I invoke a higher power is when I swear :)

I like Bo Burnham's titles (both from the song Rant):

"The Blue-balled Anti-masturbator" and "The Great All-loving F*ggot-hater"

Nature.

Asshole
Deadbeat Allfather
Holey Ghost
Sky Wizard
Santa Claus

Sky Wizard.

Who?

I mean, I do technically feel all of these names implied when talking about God, but none of them I "call" God. I guess "supreme being" would do it, I use that often even in church. I'm surprised your list doesn't have the likes of "grand unified theory", "the great white hole", "the sun", "sol invictus", "the man behind the pixels", "time incarnate", or "Morgan Freeman".

Since I just learned the word jocular right now, my answer is Jocular.

The origin point of the universe, if we lean into the secular sense

His Nibs

al-Aḥad ("The One") is nice. It's one of the 99 names of God given in the Qur-an. Coincidently, it's close to my younger cat's nickname: "One" (short for "Little One").

Transdimentional space alien

“Divinity”. “Source”
