is it okay if im a theist but not any religions?

[Darkstar]

i was christian then became atheist recently but lotta people here pointed out that i still believe in god so im probably a theist.

Yep. A theist is someone who believes in god. Doesn't have to be any specific one.

so is it okay if i just believe in god and not follow any of the religions?

Yes.

But I'm worried because christianity is the #1 religion on the planet, what if they are right? I mean, how could so many people be wrong?

How could everyone who believed in Thor and Zeus and Ra have been wrong?

And it has been around for a long time too, granted not as long as hinduism

Ra was popular for longer than Jesus has been. And that's not even considering that popularity and longevity are not indicators of whether a religion is true or not.

And they got so much organization with the Church, and so many ancient and holy scriptures and stuff too.

Church organization and the volume of their scriptures don't mean that the contents of their scriptures are accurate.

From the sound of things you aren't a deist (i.e. believe that god created the universe, but no longer interacts at all with the physical world), so I guess you're just a theist. I wouldn't worry about hell if I were you, Pascal's Wager has been long debunked anyway.
