The question: Why am I like I am? The Answer You've Been Waiting For: "The human brain is not a computer. The human brain is an irrational conglomeration of one system layered upon another. (All the animals we evolved from are there, in some fashion, in our brains.)" This is from The Healing Brain, edited by Robert Ornstein and Charles Swensionis (1990).
Regardless of your religion, your non-religion, your race, sexual orientation or gender, you're here. You made it through some 14 billion years of cosmic construction to emerge into the being you see in the mirror. Every atom in your body came forth at the beginning of everything. Yeah, you read that right. You have been around since the dawn of time and space. And, since energy is neither created nor destroyed, you will, in one form or another, be around for eternity. That's not superstition; that's your reality. And every animal that has ever walked the planet--from the amoeba to the gorilla to the humpback whale who actually doesn't walk--is part of your being. And every plant, too, and all the water and chemicals and whatever else is hanging around "out there."
