Why is eternal hell necessary? (pt. 2)?

i hav been studyin the bible since i was ten years old, nd it seems that most of christian beliefs and doctrines do not originate from the bible , but stem from superstitious and pagan beliefs, such as the belief in an eternal hell or soul, which actually are more platoesk or sacrates than anything in the bible. i jus wanted to know if anyone could give me any biblical proof of these beliefs as opposed to reinforcing doctrines that i already know are a major cornerstone of the dogma i've done more of my fair research, i jus wanted to experience other christians interpretations of certain texts other than be preached to, but thanks for the earlier information!
