No people are born uncorrupted until someone decides to force their delusional beliefs on them .I think it comes down to the gullibility of the victims as to their ability to question what was taught to them

well I'm not

I think that the more people understand about the world they live in, the less need they have for a god(s) to be the answer to their problems [...or, at least, it seems that it SHOULD be that way...] Any god which 'works in mysterious ways' whenever the shit hits the fan, or 'helps those who help themselves' (and then wants credit for the person's accomplishments) seems to be phoning it in, creator-wise...But to answer the question, no...I think people are conditioned by society to 'need' spirituality...

Not really-religions are learned behavior.

No I don't . Some seem to be quite devoid of any notion of such a thing.

we are curious , imaginative and gullible . PERFECT for the men in silly hats

Mmm; would have to know more what you mean by "spiritual". Humans are evidently adventitious (seeking) and curious about the world (a winning behavior eh?). Does this include/subsume ideas about the make up of the universe? Certainly. But... is this equivalent, leaning toward "spirituality"?

isnt there studies regarding spirituality and neuroscience? And how animals are spiritual as well?

No.

We don't know why we're here or where we're headed, so it's natural for us to ask questions that cannot be answered. But I would put my trust in science and philosophy first and foremost, rather than conjuring up some supreme being in the hope that this answers all of our questions

I think back when humans wanted to know how things worked in the world, they were not so much naturally spiritual as they were naturally ignorant.
They assigned cause to concepts they were able to grasp mentally.

Modern humans continue supporting this behavior through cognitive dissonance.
