john list2=list1

That makes list2 a reference to list1, not a copy of list1.

This is one way of copying an Array:
list2 = list1.duplicate()
https://docs.godotengine.org/en/stable/classes/class_array.html#class-array-method-duplicate

Here's another way:

var list2: Array = []
for a in list1:
     list2.append(a)
