We came from chemicals that were created in stars. The original bits and pieces of the chemicals came from something that happened 14 billion years ago, generally called "The Big Bang". We do not know what "caused" the big Bang.
So if i believe a divine power created us i am an ignorant but according to you these makes complete sense even withouth any empirical evidence..... !pokerface!
