Is God's Existence Necessary?

i'm never really quite sure which way is more plausible in my own mind. So, so one thing i think sometimes is ill use the term god, god exists because god cannot not exist, ok? But, but  sometimes i think, well, maybe it's because god can't not exist that there's no explanation for god's existence. Ad,. and i almost wonder if maybe that's what you're pointing to. It does seem to me thatthe supreme nature, could explain the necessity. And to the necessity, yes. Because in an act, you want to ffirm this. Ecause, to be honest, i'm never reallyquite sure which way was more plausible
