I'm curious to see what you have to say about why we are here...
Why who is where?
Why humans exist? pure chance. And no life has "meaning" except for what you give it yourself.
Next question?
ONE: Evolution.
TWO: The Japanese concept of Ikigai is about finding your purpose or value in life.
....and, why did you ask to be here?
That is an interesting question. Did I ask to be here? If I did, 'farting around' (quoted from above) is a wonderful way to spend time.
