Can I see something 30 miles away?

Yes, you can see something 30 miles away, but it depends heavily on being high up (like on a mountain), the target being very bright (like a large fire or city lights) or large, the air being extremely clear (no pollution/haze), and the Earth's curvature not blocking your view. With perfect conditions (flat Earth, no obstructions), the human eye could theoretically spot a candle flame at that distance, but typically, at ground level, the horizon is only about 3 miles away.
