The british were not there in 1899 when colonization was being prepared[1]. Jews coexisted with the native Palestinians before the british occupation[2][3], but this clearly is something else.
Palestinians are native to the area, they were not "brought in". This is something that is well known and established except among the deniers of history.
I am not sure if we know that Palestinians are native to this area, we have many things pointing otherwise. For example waves of migrations from Arabia after the arab conquest and soldiers being given land and settled there as reward.
Your perception of colonization is a bit anachronistic. Your understanding of what colonizing means is a bit different than what they had in mind, as evident by the difference of what Zionism means and what colonization means today.
Main differences are, no host country, no goal of economic exploitation, no goal of subjugating the locals and most importantly, as a means to return a people to its historical homeland by creating a national movement. This never happened anywhere else, which means colonization is a misnomer, decolonization in this case, if was not overloaded would be the closer term, but also non-exact
We know very well in fact. The Palestinians are the original Canaanites and even descendants of the original Israelites. This is well established.
What happened is that europe continued their colonization and used what Germanhy did to the jews as yet another excuse to push the jews out of europe. They're the antisesmites: https://www.youtube.com/watch?v=u92CEAZjCOo
