Ham and his wife had grandchildren. One of his grandsons was named Nimrod.
Nimrod grew to be a very strong man, and he did not like or obey God. Nimrod taught the people false religion. The people did evil things and again made idols of wood, stone, gold and other metals. The people began to trust in the sun, moon, and stars. The people even began to believe that the sun, moon and stars were gods and that they should worship them. Nimrod helped people forget God's ways, so the people believed his lies. They worshiped false gods and idols, and trusted them instead of the true God.
False religions of men are made with the help of Satan the devil. He causes people to disobey and to rebel against God.
When we do not obey God, we cannot understand why He has made people.
