I personally tend towards the scientific so I would tend not to credit "gods" but I think CathSci has a solid question here.
I think to find your answer you must consider that we are not really so unique.
Yes we have our civilisation, communication and ability to use tools. But take a look at colonial insects (ants, bees ect.) they have civilisation just not as we might accept it. They communicate, mostly chemically as far as I know (although bees dance). Then look at many of the monkeys and apes they use sticks to fish for termites (use of tools).
If you look carefully into any aspect that you think may set humans apart from the rest of the animals you will most likely find that it is NOT unique.
Spirituality on the other hand you may argue is the big divide. Most importantly the ability to question our existence.
But without being able to communicate completely with any other animal how will we know that we really are the only ones to ask these questions?
I would suggest that you look into the behaviour and abilities of gorillas.
