I hear the word "Random" thrown about quite often when people on this forum debate. Things such as:
"Evolution works by preserving the most beneficial random mutations..."
or
"There's no way humans came about from randomness."
When any of you use the word "Random", what are you referring to? Do you believe there are unknown forces working on our physical world? Or do you perhaps believe "random" to be the culmination of simply too many variables acting on something to make easy predictions?
Or in other words, "What are all the possible sources of randomness in our world?"
