Time and timelines are simultaneous, but is there a sort of order?

Time and timelines are simultaneous, so, in this sense, aren’t human souls (those who originated here) also cosmic souls because they “will” have lives on other planets and dimensions? Is there a kind of “order”, of consequiality, even in simultainity?
And do all possible timelines have the same importance? I mean, if when we choose A also the timeline where we choose B exists/gets created, is there a difference between the two? If not, even if humanity doesn’t choose Unity, there is the timeline where it does, and viceversa, so what would be the point of all the efforts..? Thank you so much!
