The answer can only come from God. There is no way to figure it out on your own. No man can, without God.
For the answer to why you care, ask Jesus.
I was Christian for more than the first half of my life. I actually believed. I even cried at Easter for what he did for me. But I later came to believe that I had been mistaken. Jesus had his chance to answer my questions. I prefer to ask people questions who can actually answer back without having to pretend the answers come in the form of some vague emotional state.
I duno, I suppose I wasn't really a Christian and wasn't doing it right? That's what people usually say when Christians become atheist or something else along those lines.
Now, if you want to talk about god giving the answer, I have good reason to suspect that if there was a god that he wouldn't reveal himself, ever. He wouldn't for the same reasons that we wouldn't introduce ourselves to a primitive species living on another planet: Violation of sovereignty.
I suspect that discovering god would be like finding treasure at the end of a long journey. Once we discover enough about the universe/multiverse etc, we might decide to conclude it likely that it was created by some intelligent force or thing, but I don't think that thing would present itself to us, ever, directly. Nor would advanced species living elsewhere contact us, ever. They would be more responsible and considerate than that.
Its a human curiosity for humans to decide and figure out. Science is the way, the truth and the life. Our best shot at heaven is through the scientific process.
