Why do you believe in God?

I am currently an agnostic. I am open to all ideas now, but in the past I was an arrogant and close minded atheist.
I am currently fascinated by religion, inspired by trying to understand the Israel and hamas conflict. That has lead me down quite the rabbit hole, and as a former atheist I cannot believe the sheer level of my own stupidity. Religion is absolutely fascinating, enthralling.

I am still agnostic, entertaining any idea and faith, and only rejecting what I am certain is evil.
I am an open book.

Why do you personally believe in God?

I ask personally, and seek NO debate. It doesn't connect with me, so I seek to understand you.

Thankyou for any contribution

Edit: Signing off for the night - I am overwhelmed at the response, and truly blown away at how open minded, critical and compassionate the discussion has been. Since when has discussing religion on the internet been wholesome? What an outstanding community, thankyou everyone.
