Purpose is yours to make or break.

I just accept it as one of life's little mysteries.

It makes no difference at all. It all depends how you want to live.
If it makes no difference at all, because you are Dirt, then the illusion of "how you want to live" also dissolves into nihilistic dirt, Dirt. You can slam your fingers in your Overton Window, but it was all variations on dirt, Dirt. At least, that seems the conclusion of your course. With which I don't fully agree. Sure, the flesh is dirt, but our very conversation itself negates the assertion that dirt is all there is.
Stellar rays prove fibbing never pays. Embezzlement is another matter.
