Similarities Between Gilgamesh And The Bible

The Epic of Gilgamesh has a lot of similarities to the Bible. The place where I noticed the most similarities was in chapter 5. In this chapter it takes about the flood. In both the Gilgamesh and the Bible a person is approached and told to abandon the possessions they have and to build a boat. But I do not remember God asking Moses to tear down his house before he builds the arc. Also in both the person is told the exact dimensions of which to build the boat/arc. In both pieces of texts they have similar reasons why God was angry with the current state of the human race.
I found the beginning to be sort of confusing. I am not sure what the text is trying to say when I read “No son is left with his father, for Gilgamesh takes them all;

and is this the king, the shepherd of his people?” Is it describing the main god in the story or is it one of the false gods that the human race places before the main god.
Another part of the text that I am confused about is the god’s and goddesses. Would they be more comparable to the ancient Greek gods? Or are they just other gods that were a part of the culture during that time.
Overall, I thought that this text was interesting to read. It was different than I was expecting it to be. I did not expect it to be a text that would “paint” a picture for me. As I was reading a picture began to form in my head.
