What were the reasons everyone in Sodom and Gommorah were destroyed?

Genesis (13:13)

"The men of Sodom were wicked and sinners before the Lord exceedingly."

This verse doesn't say what the Sodomites did to make them such exceedingly great sinners, though most bible believers equate "Sodomite" with homosexual. (But see Ezekiel 16:49, which claims the sins of Sodom were pride, gluttony, sloth, greed, and failure to help the poor.)

Answer

The people of Sodom and Gomorrah engaged in depraved homosexual acts. God sent angels to the city of Sodom to see how bad things were: "Then the Lord said to Abraham, 'There are terrible accusations against Sodom and Gomorrah, and their sin is very great. I must go down to find out whether or not the accusations which I have heard are true.' (Genesis 18:20-21). On arriving in Sodom, the angels were met by Abraham's nephew Lot. Knowing the men of the city were sexual deviants, Lot urged these two visitors to stay at his home: "He kept urging them, and finally they went with him to his house. Lot ordered his servants to bake some bread and prepare a fine meal for the guests. When it was ready, they ate it." (Genesis 19:3). The magnitude of how sinful the men of Sodom and Gomorrah were is seen by their blatant disregard for committing a shocking act upon two men they didn't know: "Before the guests went to bed, the men of Sodom surrounded the house. All the men of the city, both young and old, were there. They called out to Lot and asked, 'Where are the men who came to stay with you tonight? Bring them out to us!' The men of Sodom wanted to have "sex" with them." (Genesis 19:4-5). Since it is only possible for a man and a woman to have sexual intercourse, the term used for two men engaging in a homosexual act is Sodomy, which derives from the word Sodom. The angels helped Lot, his wife and his two daughters out of the city, then God burned the cities of Sodom and Gomorrah. All who remained there were burned to death: "Suddenly the Lord rained burning sulphur on the cities of Sodom and Gomorrah and destroyed them and the whole valley, along with all the people there and everything that grew on the land." (Genesis 19:24-25). Homosexuality is as much a sin today as it was back then. God decreed a law against the abhorrent act: "If a man has sexual relations with another man, they have done a digusting thing, and both shall be put to death. They are responsible for their own death." (Leviticus 20:13). Scriptures taken from the 'Sunrise Good News Bible.'

Gommorah in parsi which is driven from sanskrit(ver ancient) means people who have lost their path, obviusly in ths case meaning the paht of righteousness.

You should also not the passages that refer to Sodom in Jude 1:7. Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.
