What Buddha said are also related to science and reality. Just people/monks new days they go overboard. They mix with other religion. Buddha is not god. He can be considered as scientist. People must be fascinated by what he discovered n said and considered him as god. Like his theory "action and consequence", it can be scientific. People also translate it to karma. I think this also true.
I used to be a scientific and I used to criticize religion. I used to say to my aunty that science can explain that too. Now I believe both. I believe in spirit. I believe that dark world really exist. We cannot see but it doesn't mean it does not exist. I believe that this world is not unfair because I believe in "Action and Consequence" and Karma.
