Without the presence of Intelligent Design, how would some natural human emotions be explained?
-passion (ex. For a sport, or helping people)
-enjoyment (ex. listening to music)
-love (more than just attraction)
-loyalty
-faith (ex. In Christ)
-Preference (ex. In types of food)
There are so many different feelings and emotions that every person feels. Some of which do not appear useful as far as Natural Selection.
