Would we be human though without the inherent creation of religions?
Did human species exist before religions existed. A bit tricky to say but we certainly have evidence of human species way before we have evidence of religions. So I'd suggest that yes, you can be human without the creation of religion.
And let's not forget that 'religion' isn't some objective thing. Nope it is a term that we have coined to describe certain types of societal structures and customs. Most, but not all, are based on a belief in god, but it seems to me that the definition is somewhat arbitrary and it then becomes a bit hard to argue that something so arbitrary in definition is somehow essential to being human.
But this is all on a 'meta' scale - at the level of an individual it is clear that we can be human without religion, as there are many millions of examples around the globes of individuals who are irrefutably human yet live their lives without religion. That's unless you believe the non-sense of Cardinal Cormac Murphy O'Connor that people cannot be properly human without god and religion.
As for having no societal structures, I'm not sure who's on the jury but if they are saying that we would be what we think of as human without the drive to create and live in without them, then they are a jury of idiots.
But there are individuals who believe in, and live their lives, on the basis of complete libertarian individualism. Not many, sure, but they exist living solitary lives according to their own individual choice without social structures. Those people are, of course, human and live as humans. But that approach is challenging to maintain across generations as it largely precludes the societal structures that arise and are needed within, firstly, family groups but broader society.
So can humans live as humans without societal structures - sure they can, but it is an evolutionary dead-end.
