Basic psychology actually has a quite convincing theory for feelings: they help us survive. Emotions do involve biochemical responses in the brain, not just thought. The reason we 'love' loved ones is because it aids in survival and reproduction. Mothers become attached to their children so they look after and care for them, otherwise there would be no reason for a wild animal to care for it's offspring and hence would fail to reproduce. Children become attached to their parents because they offer them protection. The same is applied to people we're in relationships with, an attachment assures we protect our partners and have someone to reproduce with.
Happiness and fear. Fear is a very clear survival mechanism, all animals experience fear in situations that threaten their lives. Happiness can be explained as a reinforcement technique applied by our own brains, if we do something beneficial to ourselves become happy. In the context of Evolutionary Theory all these emotions have evolved in order to help animals survive. A laymans example would be: which animal would last longer? One afraid of a bigger, stronger animal, or one who tries to eat it?
As for instinct...no idea, never understood how a Dolphin could learn to swim and take breaths from the surface within 5 seconds of birth.
So your going to give all the credit to molecules and atoms that created what we have today?
Also, the feelings I listed were just examples, how about explaining ALL of them...
And, your explanation didn't explain much, lol. You just basically said what each feeling is, not how they were created.
Sure, a type of love is created by a bond between two beings, but what created that bond? What created the want for a mother bear to care for her offspring than to just leave it alone after birth?
"As for instinct...no idea, never understood how a Dolphin could learn to swim and take breaths from the surface within 5 seconds of birth."
Right, and I'm sure some theory is going to come around that fits some wild description and the people who refuse to believe in God will accept it, right?
"adaptation^ the dolphin is just born with instincts that it has developed for its need to survive"
Yeah, that DOES explain a lot...of course there must not be a God...c'mon. How does that even explain how the instinct was created? By saying that something is there doesn't explain how it was created...
So, the most important question I would like to address is-
"What created the want for a mother bear to care for her offspring than to just leave it alone after birth?"
Sure, that want will eventually turn into love, but what created that inner want to care? That inner instinct?
Atoms and molecules that suddenlly came out of no where, expanded somehow for who knows how and came together over billions of years certainly did not.
