What do Atheists believe the Bible as?

[TheCarlisle]

Since the topic has shifted from how we as skeptics see the Bible to details on whether or not the exodus from Egypt really happened, here's a fun Bible fact to consider:

When the Jews entered Egypt to live, there were seventy of them.

Exodus 1:5 And all the souls that came out of the loins of Jacob were seventy souls: for Joseph was in Egypt already.

They lived in Egypt for four generations, from Jacob's sons to Moses.

Exodus 1:1 Now these are the names of the children of Israel, which came into Egypt; every man and his household came with Jacob.
Exodus 1:2 Reuben, Simeon, Levi, and Judah,
Exodus 6:16 And these are the names of the sons of Levi according to their generations; Gershon, and Kohath, and Merari:
Exodus 6:18 And the sons of Kohath; Amram, and Izhar, and Hebron, and Uzziel:
Exodus 6:20 And Amram took him Jochebed his father's sister to wife; and she bare him Aaron and Moses:

To sum up: Levi -> Kohath -> Amram -> Moses. This is four generations.

When Moses led the Israelites out of Egypt, their men numbered 600K, not counting women and children.

Exodus 12:37 And the children of Israel journeyed from Rameses to Succoth, about six hundred thousand on foot that were men, beside children.

So assuming a 1:1 ration of men to women (generous since the male babies of Moses' generation were put to the sword), that's a population of 1.2 million.

So in four generations, the Egyptian-Jewish population went from 70 to 1.2 million in just four generations. This is a figure that only makes sense if every Jewish female from 15-40 were constantly pregnant with twins.

Yes that does seem a stretch. However, there were more than just descendants of Jacob who left, there were other slaves and even Egyptians. Nowhere does it say that 600 000 Jews left Egypt.
