If the Zionists did not STEAL the land to form the "illegitimate" state of Israel, what did it do?

if you trace your history back a little bit more you will find that there was no palestine but that the original maps were changed to erase israel,if you look at ancient history the jews or israel was there almos 3000 yrs ago and yes they did take it by force,but to suggest it be given back to a people who never were,why dont all europeans leave america and yes we should give texas back to its native people
