I have a question about the "Trinity"

[dolo amber]

I don't understand this concept. I know it's meant to essentially mean God, Jesus and 'the holy spirit', but what I don't get is how this works/what it means. Let me describe this as I *do* understand it and tell me what I'm missing.

Ok, there's God. He sends Jesus in human form to earth. But he's still like part of God or something. Then Jesus (the human) dies, and is resurrected as 'the holy spirit'. And after Jesus ascends into Heaven, they all become like 3 parts of the same thing. Is that even close? And if so, why do people still speak of Jesus as a separate entity?

I don't at all mean anything disrespectful, this is just a part of Christian theology I've never been able to get my head around. Any help would be appreciated.

Thanks! :hi:
