That's more than a reasonable argument, after all religion can cause people to do some pretty kooky stuff. It doesn't prove there were "sky gods",
only that these people believed there were and this was how to communicate with them. It may be a combination of things too, sight lines for
astronomical observations, communicating, shamanism, cultic practices that may have lost all meaning yet were to ingrained in their followers to be
let go.
In some areas the lines are so dense one has to wonder how many generations were overlapping one another, obscuring the work of a previous generation
with their own.
BTW, the team that discovered this has a good track record and made earlier, accepted discoveries in 2006.
