I believe what many of you have listed.
I also would add:
I believe we are more than the sum of our parts.
I believe that although humanity may never ultimately know how or why we are here, it is still better to exist rather than not imo.
I believe "being" or existence is perhaps intrinsic in the cosmos.
I believe we ultimately assign our own meaning and value to our lives for better or worse.
And like the song says,
"I believe that children are our future, teach them well and let them lead the way.
