Do you have any evidence that the Israelites were ever slaves in Egypt, let alone for hundreds of years?
So are you saying the Jews believe their history of being slaves (and the many times it was mentioned in the bible) was all made up. If you are going to make something up -- you portray yourselves as a great nation, not slaves or hungry arguing people wandering in the desert.
Are you saying this is all made up:
From the article: Bible history timeline by George Konig and Ray Konig
God promises Abraham many descendants
Abraham lived around 2100 BC in what is now Iraq. God told him to move to Canaan, which later became Israel. Unlike many people, Abraham believed in the one true God. God rewarded Abraham's faith, making him the father of a great nation (Israel), and an ancestor to the Messiah (Jesus Christ).
2000 BC (about 4000 years ago)
Jacob (Israel) is born
Jacob, the son of Isaac, who was the son of Abraham, is born in Canaan. Jacob's name is changed to Israel. (Canaan is later renamed Israel, after Jacob). He has 12 sons, for whom the 12 Tribes of Israel are named.
1900 BC (about 3900 years ago)
Joseph sold into slavery
Joseph, one of the 12 sons of Jacob (Israel), is sold into slavery by his brothers, who are jealous of him. Joseph ends up in Egypt, where he rises to power as a trusted assistant of a pharaoh. His father and his brothers later leave Canaan, because of a famine, and move to Egypt. They are later saved from harm by Joseph.
1446 BC (about 3400 years ago)
Exodus begins
The Hebrews, or Israelites (descendants of Jacob), are enslaved for 400 years in Egypt until Moses leads them out of Egypt. They wander the desert for 40 years. Moses then brings them to the border of Canaan, the land that God had previously promised to their forefather Abraham.
1406 BC (about 3400 years ago)
Israel begins establishing itself as a sovereign country
After Moses dies, Joshua leads the Israelites into Canaan and begins conquering the land, establishing a sovereign country of Israel for the first time in history.
