The Short Answer
Humans are not really that far ahead on raw cognitive ability; they've simply had more time where there wasn't a dominant species interfering with their access to resources to develop their tools in relative peace. Lots of apes, for example, show tool use and the basics of communication, so they're not very far behind – a few hundred thousand years to a million – which is somewhere between 0.001% and 0.033% of the time life has been on Earth. I mean, other apes are practically on top of us, evolution-wise, and even things like octopuses and dolphins aren't *that* far off. What makes it *seem* so disparate is that the last few tens of thousand years have led to a massive aggregation and refinement of technology in humans, now that we've figured out stable systems to pass on what we learn. Edit: changed wording of first sentence for clarity.
