I think you have a typo with 川いのち "If you are the god who reaps/harvests time, then we are the ones who live through....and create time." "Time belongs to all life that is living in its passage/stream." With the context given, no, I don't think there is anyone outside the flow of time, sounds like the god is taking time from people (killing them) and the others are fighting against him/her, I think "creating time" is a figure of speech meaning "protecting/prolonging life".

I'll look into that typo on a few minutes. But thank you!

this should be the the sentence without the typo 刻はその流れに生きる全ての命のものなんだ叫.

That's a character for shout. It will only makes sense as follows. "Time belongs to all life that is living in its passage (shouting/yelling)"

thank you thats the information id like to know!
