It is hard for some people to grasp the concept of souls because their rigid belief in science without God limits their minds. But, there is an important thing that everyone should realize: science is very limited itslef and we dont even know all the unexplained secrets in Earth, let alone the entire universe.
Materialist science that has no belief in souls or in God is like a man who spent his entire life inside a closed room with no windows to see the outside world. Then this man claims that the world is only the room where he lives and that there is no outside world. Similarly, our science is limited to what we see in the universe and there is no scientific evidence to DISprove the existance of souls or supernatural powers.
