Ok, the questions of why we exist,
I exist because my mother and father had sex and she became pregnant.
You are assuming there is a 'meant to be'. What makes you think the question isn't assuming more than is valid? maybe we just 'exist' and don't have a purpose. Can you show that we do?
What my grandmother intended for me is irrelevant to me now. She doesn't get to decide what my goal in life is. For that matter, even if there was a God, that God would not get to make such decisions either.
how the universe got here,
Why do you think there was a 'how' involved? Maybe the universe 'just exists'.
You mean, other than our own decisions to give it meaning? Why would you think more is required? Why do you think that life only has meaning if it has cosmic significance? That seems, to me, to be a very wrong way to approach meaning in life.
whether we are truly loved by anyone.
I guess it depends on the person and what you mean by 'truly loved by'. Some of us are lucky and find love from other people in life.
. I can go on. Want to find the answers? Start with scripture, asking God for discernment.
I think these questions assume more than they should and therefore don't have an answer of the sort you search for. Ultimately, in my opinion, you are asking the wrong questions and missing the point in doing so.
I don't assume that I am important on a cosmic scale. I don't even assume humanity is important on a cosmic scale. But that doesn't mean we are important to us, right here, right now.
I don't assume I have a 'purpose in life' that is decided by anyone other than me. it is a significant responsibility to decide what you want to do in your own life. But doing so, I have found, leads to a much richer life than attempting to discern the intentions of a supernatural being that you can't know exists in the first place.
