To put what you've said in a nutshell - some people are right, some people are wrong, and sometimes, they are neither right nor wrong, just depends which side one is on, there may be no clear line between.
We were only "cave-men" somewhere along the line between early men and modern men. But we once were. We left drawings on the walls in some caves. We evolved along the way.
Our developed senses, thoughts, and other faculties developed as we progressed. We learnt agriculture, and along with that we developed practices to accompany the time of harvests, to celebrate the results. Rituals, dances, poetry and music also were developed as we progressed. God didn't design them for us.
And that "created in his image" is nonsense. You've been infused with imagery from renaissance artists who drew/painted God as an elderly male being. If your god existed, he (or rather, it) is genderless. I never dismissed the possibility that there could be a mind behind all this we see around us. But if there was, it is not the god and his "goodness for mankind" as described in the bible.
Cheers!
You are confused between beliefs and reason. There are all kinds of beliefs under the sun. Whatever you think of those believers, they have rationalised it for themselves that their actions are justified. We may think it is irrational but they think otherwise. Anyway, my point is to tell you that all humans have rational faculties and the atheists is unable to account for it.
When you say we are more evolved and developed in our brains than animals, you again beg the question of assuming evolution to be true when that is what is needed to be shown. How do you know that we have indeed evolved from cave men? You don't, you assumed as true the story that evolution tells.
Anyway, there is no dispute that our brains are more complex and advanced compared to the animal kingdom. You believe that is because we have evolved further, but you cannot explain where these faculties come from. I believe that is because we are created/designed that way, being made in the image of God. It makes better sense to believe that there is a Mind behind alll these than to believe that mere mindless matter can produce the brain and reasoning abilities.
