In some ways, to believe in evolution is almost like a following; a cult following - if you don't believe in evolution, you're considered completely backward. That seems to me very indicative of bias as well.
You cannot stay on the summit forever; you have to come down. . . So why bother in the first place? Just this: What is above knows what is below, but what is below does not know what is above. In climbing, take careful note of the difficulties along your way; for as you go up , you can observe them. Coming down, you will no longer see them, but you will know they are there if you have observed them well.
