I don't get this analogy
Not trying to sound mean or anything, but I don't understand what you're trying to say? My understanding of what you said is that we're humans, and over time, we interact with a greater audience of people. Then you say... we're humans, therefore we will never understand the origin of our creation, but take solace in knowing that there is a being greater than us?
If we don't understand the origin of our creation, how do we know there's an "advanced species", or in other words, a God?
Just because we don't understand our creation now, doesn't mean we wont be able to in the future. There's been so many technological advances in such a short period of time, who knows, we may find the origin of the universe sooner than we think.
I don't think it's right to assume there is a greater being that created all of this just because we can't explain or understand things yet.
