Agreed, it's necessary to ponder our existence so we can grow.
While String Theory is not a proven fact, my rational brain feels that it's currently the best explanation. Everything is vibration, which emits a specific frequency. As each compatible frequency combines in the micro, we see the diverstity in the macro.
The simplicity of the perceived complexity is mind-blowing.
And don't forget how we break down our food for fuel. Our bodies don't do it alone. It works with many separate entities in harmony for mutual benefit. It would be nice if we could achieve this same harmony with our fellow species.
