I'm also not one to spend much time or thought trying to figure out and understand "why". Nonetheless...
I guess for me it's just always been a part of my personality to make art, solve puzzles, invent, engineer, embrace technology, and learn all I can about everything that catches my interest. It's just who I am. Photography has engaged all those facets of what makes me who I am.
I don't know what percent of that is nurture vs. nature, but I grew up in a family full of painters, sculptors, poets, writers, musicians, photographers, inventors, engineers, puzzle-masters, intellectuals, and the like. Surrounded by people doing all that stuff from birth who encouraged and taught and made the experiences joyful with me and for me, I've found personal joy and fulfillment and satisfaction in doing all that stuff over the course of my entire lifetime.
For about 46 years and counting, photography as a tool for making art has been one of the main things I do that fulfills that side of me, so I continue to do it.
