Actually, one of those sky monsters is well over two thousands years old, the other is only 1300 years old. But why do they need tables when they have perfectly good tummies?

Respectfully, this is reductive. The I/P conflict is about 75 years old by most official metrics, arguably a bit north of 100 years old depending on how one defines their terms.

The conflict is largely political and ethnic, religion's role is largely tactical and context-specific. The first Jews coming to the Old and New Yishuv were generally either secular, or refugees (aka, not super concerned with religion so much as safety).

Palestinians in the area are responding to what they view as colonialism, not some divine mandate against Jews (although that is absolutely present on the extreme end).

Not every evil comes down to religion. The world, unfortunately, is not so simple as to rest all the world's evils at the feet of one concept.
