I believe a higher power, be it God or something else, influenced the creation of mankind through evolution.
In escence, I think the development of humans from simple organisms to their current state couldn't have been done by chance.
Like you, I haven't really indulged in bible study since Sunday School, which I last attended when I was 13.
Could the teachings of Christ be true? Sure.
But I just find it hypocritical that most people are taught to shun past and foreign civilizations that are polytheistic or have other religious beliefs.
Nobody will ever know for sure why we're really here. Might as well pick a religion and stick with it.
