Questions about Israel and Christians?

kinda long but i got a point?bear with me.i always hear ppl say that jews belong in Israel because its "their homeland" but what are the reasons for this? is it because of the culture? well is jewish culture 100% middle eastern??i think not goldberg,silverman, bernstein dont sound hebrew to me. yiddish isnt pure Semitic. ok so if its not the culture then it must be the scripture correct? because their religion says thats their homeland and thats where it began. but how come Christians dont have a right to it? isnt that where Christianity began the first Christians werent anglo saxsons LOL.the homeland of all christians is technically Israel.but wait before Judaism even began who did it belong to? a bunch of barabric pagans? or maybe this is all religious bull hockey and ppl try to justify anything and separate others with it?should america give money to Israel?does palestine have a right to claim that land? didnt they invade it too? and before it belonged to jews who had a right to it?the Egyptians?the sumerians,babylon?or the peasants who were pagan?
