Welcome to agnostic, @belly66 . But do you believe the first sentence in Neil Tyson’s Astrophysics for People in a Hurry?

“In the beginning, nearly fourteen billion years ago, all the space and all the matter and all the energy of the known universe was contained in a volume less than one-trillionth the size of the period that ends this sentence.”

That’s almost as hard to believe as the trinity and a virgin birth, @belly66 . It does keep homo sapiens at the center of things.

The Big Bang wasn't really an explosion in any sense of the word, but yes, an amazing thing, far grander that the comic book creation myths people came up with in the early Iron Age.
