The problem is we ask the wrong questions. Why are we here? what is the reason? That trips us up because we want some sort of ego gratifying greater reason and we don't have one.
Perhaps the only reason we are here is because whatever forces that brought us into being (and I'm speaking of the physical forces of the universe here, not an intelligent God), caused us to be here. Simple cause and effect. This does not have to have some greater intent or intelligence behind it.
For example, If I come into a room and find a bag of rice spilled all over the floor, I can ask myself, how did this happen? What caused it? What is the reason for it? The reason may be so simple as a strong gust of wind came through the window and blew it over. The wind doesn't have intelligence or design or intent behind it. It just blows....
I can spend the rest of my day in a state of internal angst, trying to figure out the reasons why the wind did this, what greater meaning is there in it all, or, I can pick up the rice, put on a pot of water to boil and think about how to best enjoy eating it.
It's like that question often asked of mountaineers, "why do you climb mountains?" Because they are there! Why did the chicken cross the road? To get to the other side. Silly.
We ask the wrong questions. Always asking why, why? Better questions would begin with how. I am here, regardless of why, how can I enjoy this experience and how can I help others to enjoy it more also? Instead of why do people suffer? ...How can I avoid the many pitfalls of suffering that plague so many humans unnecessarily?
Children ask why, why, why? Grownups ask how, how, how?
