The bible: Stolen stories through history?

In ancient egyptian history(2000 years before christianity) the story of horus was told. He was crucified, had 12 disciples, and had the title messiah, and was ressurected in 3 days. The story of gilgamesh(more ancient history, again 2000 years before christianity) is the EXACT SAME story as noah's ark!!! And as for the story of Sodom and Gommorah, when the angels told god there wasnt 10 good souls there, Did babies not count?!?!? What about children, they are supposed to be pure! YEt god supposidly killed them all(baby killer). Any christians wanna make a comeback on this?
