I think the large trash is called Gehenna. Hell originates from a hebrew word hades meaning grave. In Greek mythology, the god of death is called hades.
I have always questioned it existence with these questions:
When was it instituted?
where is hell?
If its such a place for bad people, why does the bible account tells us that Jesus went to hell and overcame death and got the key of life?
I love your write up. keep educating.
KUDOS!
Thank you
