Three possibilities come to mind:
Is there an evolutionary purpose?
Does it arise as a consequence of our mental activities, a sort of side effect of our thinking?
Is it given a priori (something we have to think in order to think at all)?

No, but you have the ability to sense your heartbeat, so you can tell that it’s there.
You don’t have the ability to sense electromagnetic emissions in the X-ray frequency range, so you can’t tell that they’re there. You wouldn’t know if X-rays of a given intensity were present at a given moment. It’s like asking “why is there the illusion that there are no X-rays” when you wouldn’t expect to feel differently regardless of their presence or non-presence.
