Why did we "assume" that there were spirits, gods, and the supernatural in the first place?

Question

Do animals have any type of religion?

How did people acquire it?

Is it related to developing speech and writing?

Can we ever know the real answer to this for certain?

Answer 1

It's because people need to blame all their problems on someone else, and they need an excuse to act like they should. Christians won't have s*x until they were married if they think they're going to Heaven. None of it's real.

Answer 2

"we" will never know the  answer to a question that can only be answered individually.

Answer 3

I think it's because people have also wondered how we came to be, how everything was made and it was just an easier thing to understand then all the science or the not knowing.
